**Activate in each vault:** Open the vault → **Settings → Appearance → Themes → Manage** → `Challenger Deep` should be in the list (it'll appear under the *installed* section since it's already in the themes folder, not the community gallery). Click **Use**.

The third vault `~/Documents/notes/` looks dormant (workspace last touched 2024-05-30) so I left it alone. If you want it there too:
```
\cp -r ~/.config/themes/obsidian-challengerdeep ~/Documents/notes/.obsidian/themes/Challenger\ Deep
```

**Mapping notes**
- Dark only — toggling Obsidian to light mode falls back to Obsidian's default light theme rather than producing washed-out garbage. Cleaner UX than half-implementing a light variant of a fundamentally dark palette.
- Three-tier surface system: `--background-secondary #16131f` (sidebar/ribbon — darker than the editor), `--background-primary #1b182c` (editor — palette bg), `--background-primary-alt #2a2640` (elevated/hover). Sidebar darker than editor mirrors the Obsidian convention so your eyes track focus correctly.
- **`--interactive-accent`** is `dark_magenta #906cff` (same signature accent across every theme this session). Hover state warms to `magenta #c991e1`.
- **`--text-on-accent` is palette black `#100e23`** — text rendered on top of the bright accent (selected file, default buttons) gets dark text rather than light, which is dramatically more readable.
- **Headings rotate through six palette colors** (H1 magenta → H2 blue → H3 dark_cyan → H4 dark_green → H5 yellow → H6 dark_yellow). Color-coded heading hierarchy that doesn't rely on size alone.
- **Code block syntax**: keywords magenta, strings green, functions yellow, comments gray italic — same mapping as the GoLand `.icls`, so code looks the same in your editor and your notes.
- **Callouts** are mapped semantically per type: info→blue, success→green, warning→orange, error/danger→red, tip→cyan, example→magenta. Obsidian's callout contract takes RGB tuples (no `#`), which is what those `--callout-*: r, g, b` lines are.
- **Selection / highlight** use semi-transparent palette colors (`rgba(144,108,255,0.35)` for selection, `rgba(255,233,170,0.25)` for `==marks==`) so they tint without obliterating the underlying text.
- A handful of explicit selectors at the bottom cover things variables don't reach: active editor line tint, active tab strip, file explorer selection. Without them, those surfaces stay un-themed.

You're porting the Challenger Deep palette across all your tools and just finished the Obsidian theme (installed in the home and docs vaults). Next: open Obsidian, Settings, Appearance, Themes, Manage, and select Challenger Deep to activate it.

can you create a claude code theme for challenger deep?


Before I build anything, let me verify what theme customization Claude Code actually supports — it has a fixed set of built-in themes selected via `/theme`, but I want to confirm whether custom theme JSON is a thing now.

---
Usage: claude [options] [command] [prompt]

Claude Code - starts an interactive session by default, use -p/--print for
non-interactive output

Arguments:
  prompt                                            Your prompt

Options:

  --agent <agent>                                   Agent for the current session. Overrides the 'agent' setting.
  --agents <json>                                   JSON object defining custom agents (e.g. '{"reviewer": {"description": "Reviews code", "prompt": "You are a code reviewer"}}')
  --allow-dangerously-skip-permissions              Enable bypassing all permission checks as an option, without it being enabled by default. Recommended only for sandboxes with no internet access.
  --allowedTools, --allowed-tools <tools...>        Comma or space-separated list of tool names to allow (e.g. "Bash(git *) Edit")

  --bare                                            Minimal mode: skip hooks, LSP, plugin sync, attribution, auto-memory, background prefetches, keychain reads, and CLAUDE.md auto-discovery. Sets CLAUDE_CODE_SIMPLE=1. Anthropic auth is strictly ANTHROPIC_API_KEY or apiKeyHelper via --settings (OAuth and keychain are never read). 3P providers (Bedrock/Vertex/Foundry) use their own credentials. Skills still resolve via /skill-name. Explicitly provide context via: --system-prompt[-file], --append-system-prompt[-file], --add-dir (CLAUDE.md dirs), --mcp-config, --settings, --agents, --plugin-dir.

What would you like to configure, Sir Charles of St Cheese? A few possibilities:

- **Claude Code settings** (`settings.json` — permissions, hooks, env vars, model)
- **Keybindings** (`~/.claude/keybindings.json`)
- **Status line** appearance


That kicked off the update-config skill but didn't tell me what I needed. Let me ask the Claude Code expert agent definitively whether custom themes are even a thing.


Agent

Verify Claude Code custom theme support

Prompt:
I need a definitive answer about Claude Code's theme customization, current as of late 2025 / early 2026 (Claude Code 2.1.126).

Specifically:

1. What are the built-in themes accessible via `/theme` or settings.json's `theme` field? List them all.

2. Does Claude Code support **user-defined custom color themes** — i.e., can a user supply a JSON file or inline definition that maps Claude Code's UI elements (prompt, syntax highlighting in code blocks, tool-use indicators, diff colors, status line, etc.) to arbitrary hex colors? If yes, give me the schema/file location/exact mechanism.

3. If custom themes aren't supported, what's the closest workaround? I'm thinking the answer is "Claude Code uses ANSI colors that follow the user's terminal scheme" — confirm or correct that.

4. Is there any way to override individual colors (not a full theme) — e.g., just the prompt color, just the diff colors? Hooks? Settings? Env vars?

I'm asking because a user wants me to "create a Claude Code theme" with a specific color palette, and I want to give them an honest answer about what's actually possible rather than fabricating a non-existent feature. Please report under 250 words.


Excellent. I now have all the information needed to provide a definitive answer. Let me compile the findings.

## Definitive Answer: Claude Code Theme Customization (v2.1.126)

**1. Built-in themes:**
Claude Code ships with 6 preset themes accessible via `/theme`:
- `dark` (default)
- `light`
- `dark-daltonized` (colorblind-friendly)
- `light-daltonized` (colorblind-friendly)
- `dark-ansi` (terminal-aware)
- `light-ansi` (terminal-aware)

**2. Custom themes—YES, fully supported (v2.1.118+):**
Users CAN create custom color themes. Implementation:
- Create JSON files in `~/.claude/themes/`
- Each file = one theme with `name`, `base` (preset), and `overrides` (color token map)
- Interactive editor: select "New custom theme…" in `/theme` to build one step-by-step
- Supported color formats: `#rrggbb`, `#rgb`, `rgb(r,g,b)`, `ansi256(n)`, or `ansi:<name>`
- Live reload: changes apply immediately without restart
- Pressable: distribute custom themes via plugins

**3. Color tokens (token reference):**
40+ tokens cover every UI element: `claude` (brand accent), `text`, `error`, `success`, `diffAdded`, `diffRemoved`, `userMessageBackground`, `promptBorder`, `planMode`, `pathBorder`, and more. Full list in the accordion at https://code.claude.com/docs/en/terminal-config.md#color-token-reference

**4. Terminal interaction:**
Claude Code uses ANSI colors that respect the terminal's configured palette. The `dark-ansi` and `light-ansi` presets map to standard 16-color ANSI names. The theme system does NOT control the terminal's own color scheme (that's the terminal app's responsibility).

**5. Individual color override:**
Not separately—users must define a theme (even a sparse one) to override specific tokens. No per-color env vars or hooks.

**Bottom line:** Tell your user they can absolutely create a custom theme with their exact color palette. Point them to `~/.claude/themes/` and the schema example at https://code.claude.com/docs/en/terminal-config.md. They can use the interactive `/theme` UI or hand-edit JSON. No fabricated features needed.

Custom themes are fully supported. Let me grab the full token reference so I cover every UI element.


Bash

curl -fsSL https://code.claude.com/docs/en/terminal-config.md 2>/dev/null | sed -n '/color token/,/^## /p' | head -250

Fetch Claude Code color token reference


In addition to the built-in presets, `/theme` lists any custom themes you have defined and any themes contributed by installed [plugins](/en/plugins-reference#themes). Select **New custom theme…** at the end of the list to create one interactively: you name the theme, then pick individual color tokens to override. Press `Ctrl+E` while a custom theme is highlighted to edit it.

Each custom theme is a JSON file in `~/.claude/themes/`. The filename without the `.json` extension is the theme's slug, and selecting the theme stores `custom:<slug>` as your theme preference. The file has three optional fields:

| Field       | Type   | Description                                                                                |
| :---------- | :----- | :---------------------------------------------------------------------------------------------------------------------------------------------- |
| `name`      | string | Display label shown in `/theme`. Defaults to the filename slug                                                                                |
| `base`      | string | Built-in preset the theme starts from: `dark`, `light`, `dark-daltonized`, `light-daltonized`, `dark-ansi`, or `light-ansi`. Defaults to `dark` |
| `overrides` | object | Map of color token names to color values. Tokens not listed here fall through to the base preset                                                |

Color values accept `#rrggbb`, `#rgb`, `rgb(r,g,b)`, `ansi256(n)`, or `ansi:<name>` where `<name>` is one of the 16 standard ANSI color names such as `red` or `cyanBright`. Unknown tokens and invalid color values are ignored, so a typo cannot break rendering.

The following example defines a theme that keeps the dark preset but recolors the prompt accent, error text, and success text:

```json ~/.claude/themes/dracula.json theme={null}
{
  "name": "Dracula",
  "base": "dark",
  "overrides": {
    "claude": "#bd93f9",
    "error": "#ff5555",
    "success": "#50fa7b"
  }
}
```

Claude Code watches `~/.claude/themes/` and reloads when a file changes, so edits made in your editor apply to a running session without a restart.

The reference below covers the tokens you can set in `overrides`. The interactive editor in `/theme` shows the same tokens with a live preview, plus a few single-purpose accents such as onboarding screen colors that are omitted here.

<Accordion title="Color token reference">
  The following example combines tokens from several of the groups below: the brand accent, the plan mode border, the diff backgrounds, and the fullscreen message background.

  ```json ~/.claude/themes/midnight.json theme={null}
  {
    "name": "Midnight",
    "base": "dark",
    "overrides": {
      "claude": "#a78bfa",
      "planMode": "#38bdf8",
      "diffAdded": "#14532d",
      "diffRemoved": "#7f1d1d",
      "userMessageBackground": "#1e1b4b"
    }
  }
  ```

  #### Text and accent colors

  Control the primary brand accent and the foreground text shades used throughout the interface.

  | Token         | Controls                                                         |

  #### Usage meter and speaker labels

  Adjust the bar shown in the `/usage` view and the labels that distinguish your messages from Claude's.

  | Token              | Controls                                          |

  | `briefLabelYou`    | Color of the `You` label on your messages         |
  | `briefLabelClaude` | Color of the `Claude` label on assistant messages |

  #### Shimmer variants and subagent colors

  Several tokens have a paired shimmer variant that supplies the lighter color used in the spinner's animated gradient. Override the shimmer alongside its base token if the animation looks mismatched.

  * `claude` and `claudeShimmer`
  * `warning` and `warningShimmer`
  * `permission` and `permissionShimmer`
  * `promptBorder` and `promptBorderShimmer`
  * `inactive` and `inactiveShimmer`
  * `fastMode` and `fastModeShimmer`

  Each [subagent](/en/sub-agents) and parallel task is shown in one of eight named colors so you can tell them apart in the transcript. The token names follow the pattern `<color>_FOR_SUBAGENTS_ONLY`, where `<color>` is `red`, `blue`, `green`, `yellow`, `purple`, `orange`, `pink`, or `cyan`. Override these to change what each named color looks like. For example, a subagent with `color: blue` in its definition is drawn using the `blue_FOR_SUBAGENTS_ONLY` value.

  The [`ultrathink`](/en/model-config#use-ultrathink-for-one-off-deep-reasoning) and [`ultraplan`](/en/ultraplan) keywords in the prompt input are rendered with a seven-color rainbow gradient. The token names follow the pattern `rainbow_<color>` and `rainbow_<color>_shimmer`, where `<color>` is `red`, `orange`, `yellow`, `green`, `blue`, `indigo`, or `violet`.

OK - Challenger Deep base: dark - 55 token overrides
non-hex values: none
unique colors: 24


Done, Sir Charles. 55 token overrides, 24 unique colors, all valid hex.

**File:** `~/.claude/themes/challengerdeep.json`

**Activate it right now** — Claude Code watches the themes directory for live reload, so:
1. Type `/theme` in this session
2. Scroll down past the built-in presets
3. Select **Challenger Deep**

It'll apply immediately, no restart. Setting is saved as `theme: "custom:challengerdeep"` in your settings.

**Token coverage**
- **Brand & text** (8 tokens): `claude` accent on `dark_magenta #906cff`, with `claudeShimmer` warming to `magenta #c991e1` for the spinner gradient. Text on `#cbe3e7`, inverse text on palette black `#100e23` so it stays readable on bright accent fills.
- **Status** (4 tokens): green/red/orange the obvious way; `merged` (PR merged) on `dark_magenta` to match GitHub's purple-for-merged convention.
- **Mode indicators** (6 tokens): `promptBorder` matches the brand accent so the input box reads as "this is where Claude lives", but the four mode borders are deliberately distinct hues so you can tell at a glance which mode is active — plan = `dark_cyan`, accept-edits = `dark_green` (go-go-go), bash = `dark_yellow` (warning-flavored), IDE = `blue`, fast = `magenta`.
- **Diff** (6 tokens): dim tints `#1f3a2a` / `#3a1f23` for line backgrounds (saturated palette colors as line bgs are unreadable — same constraint we hit in the GoLand `.icls`), with brighter word-level highlights `#2c5a40` / `#5a2c30` for inline emphasis.
- **Fullscreen mode bgs** (6 tokens): subtle elevated tints. Bash messages get a faint warm tint `#2c281a`, memory entries a faint cool tint `#1f2c3a` so the three message types are distinguishable at a glance even in dense transcripts.
- **Subagent slots** (8 tokens): each named color (`red_FOR_SUBAGENTS_ONLY`, etc.) maps to its closest palette equivalent. So a subagent declared with `color: blue` shows up as ChallengerDeep's `dark_blue #65b2ff` instead of generic terminal blue.
- **Rainbow** (7 tokens): `ultrathink` / `ultraplan` keyword gradient gets palette-mapped — red → dark_red, indigo → dark_magenta, violet → magenta, etc. So when you invoke deep reasoning, the rainbow is *your* rainbow.
- **Shimmer pairs** (6 tokens): every shimmery animated element (`claude`, `warning`, `permission`, `promptBorder`, `inactive`, `fastMode`) gets a paired lighter color so the spinner gradient reads correctly instead of muddy.

Tokens I deliberately didn't override (single-purpose accents the docs say are omitted from the public reference) fall through to the dark preset's defaults — which are sensible neutrals that work with this palette.

That's seven ChallengerDeep ports today: lsd, zellij, starship, GoLand `.icls`, GoLand plugin JAR, btop, Slack, Obsidian, and now Claude Code itself. Your terminal is going to be remarkably consistent.

# Challenger Deep palette — multi-tool port

## Summary
Ported the [Challenger Deep palette](https://github.com/challenger-deep-theme/themes) to nine tools in one session: lsd, zellij, starship, btop, Slack (sidebar), Obsidian, GoLand (`.icls` editor scheme + UI plugin), and Claude Code itself. Each port maps the same 16-color palette consistently so accents (focus rings, brand colors, primary actions) stay the same color across every tool.

## Context
- **Working directory:** `/Users/steve.briggs` (home — no specific project; ad-hoc theming work).
- **Platform:** macOS (darwin 25.3), zsh, most binaries via mise / homebrew / cargo.
- **Source palette (16 colors):** background `#1b182c`, foreground `#cbe3e7`, gray `#a6b3cc`, black `#100e23`, red `#ff8080`, dark_red `#ff5458`, green `#95ffa4`, dark_green `#62d196`, yellow `#ffe9aa`, dark_yellow `#ffb378`, blue `#91ddff`, dark_blue `#65b2ff`, magenta `#c991e1`, dark_magenta `#906cff`, cyan `#aaffe4`, dark_cyan `#63f2f1`.
- **Pre-existing themes (kept side-by-side, not overwritten):** lsd was on Cyberpunk; starship on a Dracula-ish "rainbow" palette; btop on Default. Zellij and Claude Code had no active custom themes.

## Decisions

### Cross-tool consistency rules
- **Signature accent: `dark_magenta #906cff`** — used as primary brand color in every tool (starship `accent`, GoLand focus rings, Claude Code `claude` token, btop `cpu_box` and `process` gradient, Slack active-channel pill, Obsidian `--interactive-accent`).
- **Hover variant: `magenta #c991e1`** — paired everywhere as the lighter accent for hover/shimmer states.
- **Inverse text on accent: palette black `#100e23`** — not foreground, since dark-on-bright reads dramatically better than light-on-bright at small sizes (used in Slack active-item text, Obsidian `--text-on-accent`, Claude Code `inverseText`, GoLand default-button fg).
- **Selection / mid-tone surface: derived `#3b3470`** — palette has no native selection color, so we picked the value commonly used by ChallengerDeep's terminal/Vim themes. Same value used everywhere for consistency.
- **Elevated surface: derived `#2a2640`** — between bg and selection for hovers, popups, elevated panels.
- **Dim text: derived `#5a5475`** — inactive items where palette gray `#a6b3cc` is too bright.

### Gradient strategy (btop, GoLand, Claude Code rainbow)
- **Severity ramps** (where high = bad): green → yellow → red. Used for CPU load, temperature, memory used, error severity.
- **Color-family ramps** (purely aesthetic, not severity): single-hue brightness ramps. Used for free memory, cached, available, network up/down, process gradient.

### Tool-specific design
- **lsd:** uses RGB arrays `[r,g,b]` — lsd's deserializer accepts named-color strings, single u8, or 3-element array, but **not** `#rrggbb` strings. Schema has `deny_unknown_fields` and `file_type` is `#[serde(skip)]`, so including a `file-type:` block crashes the parse — file-type colors come from `LS_COLORS`.
- **Zellij:** simple 16-color form with hex strings; the newer multilayer styled form (`text_unselected`, `ribbon_*`) is supported but overkill.
- **Starship:** added `[palettes.challengerdeep]` block alongside the existing `rainbow` palette; user flipped `palette = 'challengerdeep'` themselves mid-session.
- **GoLand:** delivered both standalone `.icls` and packaged plugin JAR. `.icls` uses `parent_scheme="Darcula"` so unhandled tokens fall back. Plugin JAR contains the `.theme.json` (294 UI keys), the color scheme as `.xml` (bundled schemes drop the `.icls` extension), and `META-INF/plugin.xml`.
- **Slack:** only themes the sidebar; the message panel/composer is uncontrollable. Theme is just an 8-color comma-separated string pasted into preferences.
- **Obsidian:** dark-only theme. Switching app to light mode falls back to default light rather than half-implementing a washed-out variant.
- **Claude Code:** verified custom theme support via claude-code-guide agent — `~/.claude/themes/<slug>.json` with `name`/`base`/`overrides`. Live reload, no restart needed.

## Task State

### Completed — files written and validated
| Tool | Path | Status |
|------|------|--------|
| lsd | `~/.config/lsd/colors-challengerdeep.yaml` | parses under lsd 1.2.0 (swapped, ran `lsd`, restored) |
| Zellij | `~/.config/zellij/themes/challengerdeep.kdl` + `~/.config/zellij/config.kdl` | parses under zellij 0.40.1; **active** (no prior theme) |
| Starship | `~/.config/starship.toml` (added `[palettes.challengerdeep]` block) | parses under starship 1.19.0; user **flipped to active** |
| btop | `~/.config/btop/themes/challengerdeep.theme` | 42/42 keys, zero diff vs canonical schema |
| Slack | `~/.config/themes/slack-challengerdeep.txt` (reference + the 8-color string) | string ready to paste |
| Obsidian | `~/.config/themes/obsidian-challengerdeep/{manifest.json,theme.css}` | 125 CSS vars, balanced braces |
| Obsidian (deployed) | `~/Documents/obsidian/{home,docs}/.obsidian/themes/Challenger Deep/` | dropped into both active vaults |
| GoLand `.icls` | `~/Library/Application Support/JetBrains/GoLand2024.3/colors/ChallengerDeep.icls` | 24 editor + 103 syntax keys, valid XML |
| GoLand plugin | `~/Downloads/ChallengerDeep.jar` | plugin.xml + theme.json + bundled scheme; 294 UI keys |
| Claude Code | `~/.claude/themes/challengerdeep.json` | 55 token overrides, 24 unique colors, all valid hex |

### Activated this session
- Zellij (config.kdl + theme dropped, active by default since no prior config)
- Starship (user flipped `palette = 'challengerdeep'` themselves)

### Pending user activation
- **lsd:** `\cp ~/.config/lsd/colors.yaml ~/.config/lsd/colors-cyberpunk.yaml && \cp ~/.config/lsd/colors-challengerdeep.yaml ~/.config/lsd/colors.yaml`
- **btop:** `o` → Theme → `challengerdeep`, OR edit `color_theme = "challengerdeep"` in `~/.config/btop/btop.conf`
- **Slack:** Preferences → Themes → Create new theme → paste `#1b182c,#3b3470,#906cff,#100e23,#2a2640,#cbe3e7,#62d196,#ff5458`
- **Obsidian:** in each vault, Settings → Appearance → Themes → Manage → Challenger Deep → Use
- **GoLand `.icls`:** Settings → Editor → Color Scheme → ChallengerDeep
- **GoLand plugin:** Settings → Plugins → ⚙ → Install Plugin from Disk → `~/Downloads/ChallengerDeep.jar`
- **Claude Code:** `/theme` → scroll past presets → Challenger Deep

## Open Questions
- **GoLand UI plugin** validates structurally (XML/JSON parse, palette references resolve, 294 UI keys covered) but was not launch-tested — the IDE silently falls back to platform defaults for any missing/wrong key. There are 800+ possible UI keys; ~290 covered. Surfaces that may still look Darcula-ish are unknown until run.
- **Obsidian dormant vault** (`~/Documents/notes/`, last touched 2024-05-30) was deliberately skipped. If revived, copy theme dir from `~/.config/themes/obsidian-challengerdeep/`.
- Whether to also produce a matching **`LS_COLORS`** string so file-type coloring in `lsd` matches the same palette (offered, user did not request).

## Next Steps
1. Activate the pending themes in each tool (list above) and live-test.
2. **GoLand plugin live test**: install the `.jar`, restart, eyeball the UI. Report any surfaces that still look Darcula-ish (specifically: tool windows, kebab menus, version control sidebar, debug panel, file diff gutter) and the missing keys can be added.
3. If the user wants the dormant `notes` vault themed too: `\cp -r ~/.config/themes/obsidian-challengerdeep ~/Documents/notes/.obsidian/themes/Challenger\ Deep`
4. Optional follow-on: matching `LS_COLORS` for file-type coloring in lsd.
5. Optional follow-on: tweak any specific surface that doesn't read well in practice — palette swaps are localized in each theme file (the design is consistent enough that "tweak the accent" or "darken the box surface" is a one-line edit per tool).

## Reference: canonical source paths
- Re-deployable Obsidian bundle: `~/.config/themes/obsidian-challengerdeep/`
- Slack theme string + slot mapping: `~/.config/themes/slack-challengerdeep.txt`
- Plugin JAR (re-installable): `~/Downloads/ChallengerDeep.jar`
- All other themes live where the tools expect them; no separate canonical source.

Saved to `Claude/themes/2026-05-04-challenger-deep-port.md` in your Obsidian vault. Captures the full session: nine theme ports with files/paths/validation status, the cross-tool consistency rules (signature accent, derived selection mid-tone, severity vs aesthetic gradients), tool-specific schema gotchas worth remembering (lsd not accepting hex, GoLand's `serde(skip)` on file-type, etc.), pending activations, and the one outstanding loose end (GoLand UI plugin not launch-tested).


Goal was porting the Challenger Deep palette to your dev tools; we shipped nine themes (lsd, zellij, starship, btop, Slack, Obsidian, GoLand scheme + plugin, Claude Code) and saved a session note to Obsidian. Next, activate the pending themes per the recap.


can you also create a challenger deep theme for fzf ?


Let me check fzf version and current setup before designing.


command -v fzf && fzf --version
echo '---'
echo "FZF_DEFAULT_OPTS: ${FZF_DEFAULT_OPTS:-(not set in this session)}"
echo '---'
# Check zshrc for fzf-related settings (read-only, just looking)
grep -inE 'fzf|FZF_' ~/.zshrc ~/.zshenv ~/.zprofile 2>/dev/null | head -20

Check fzf install, version, and current configuration


fzf 0.54.0 — supports every modern color token including `separator`, `scrollbar`, `preview-*`, `label`. Hex fully supported. Current `FZF_DEFAULT_OPTS` is uncolored, set on line 159 of your `.zshrc`. I'll save the theme as a sourceable snippet — won't touch `.zshrc` without your say-so.

---fzf exit: 0


fzf parsed the colors cleanly (exit 0), filtered for `eta` and returned `beta` as expected. Theme is valid under fzf 0.54.0.

**File:** `~/.config/themes/fzf-challengerdeep.sh`

**Activate it** — append one line to your `~/.zshrc` *after* the existing `FZF_DEFAULT_OPTS` export at line 159:
```sh
. ~/.config/themes/fzf-challengerdeep.sh
```
The snippet appends to whatever `FZF_DEFAULT_OPTS` already holds, so your `--height 40% --layout=reverse --border` is preserved. Open a new shell or `source ~/.zshrc` to apply.

**Mapping notes**
- **`bg=-1` / `gutter=-1` / `preview-bg=-1`** — terminal-default backgrounds (transparent), inheriting your existing terminal scheme. Replace with `#1b182c` if you ever want the theme self-contained, but since your terminal is already on a ChallengerDeep-style scheme, `-1` keeps it honest.
- **Match highlights**: `hl=#ffe9aa` (yellow) on non-current items, `hl+=#ffb378` (dark_yellow) on the selected line — slightly more saturated so the cursor's row visually leads.
- **`prompt=#906cff`** — signature accent (same `dark_magenta` as everywhere else this session). The `>` prompt symbol carries the brand.
- **`pointer=#c991e1`** — magenta pointer on the current item. Pairs with prompt as accent/hover variant.
- **`marker=#62d196`** — `dark_green` for multi-select markers (`Tab`-toggled items). Green is the universal "yes, this one" signal.
- **`header=#63f2f1`** — `dark_cyan` for the optional header line. Distinct from prompt/pointer so you can tell at a glance whether you're in a normal fzf or one with a header.
- **`disabled=#5a5475`** — derived dim for disabled items (e.g., when you're typing a query that's filtering out non-matches in some pickers).
- **Borders / separators / scrollbars all on `#3b3470`** — the same derived selection mid-tone we use as the universal subtle-but-visible color across every theme today. Frame elements stay quiet so colored content (matches, accents) leads.
- **Preview pane** uses the same color system as the main window — borders match, label dim, scrollbar same. So if you have `fzf --preview ...` running, both panes feel like one widget rather than two separately-themed boxes.

# Challenger Deep palette — multi-tool port

## Summary
Ported the [Challenger Deep palette](https://github.com/challenger-deep-theme/themes) to **ten tools** in one session: lsd, zellij, starship, btop, Slack (sidebar), Obsidian, GoLand (`.icls` editor scheme + UI plugin JAR), Claude Code itself, and fzf. Each port maps the same 16-color palette consistently so accents (focus rings, brand colors, primary actions) stay the same color across every tool.

## Context
- **Working directory:** `/Users/steve.briggs` (home — no specific project; ad-hoc theming work).
- **Platform:** macOS (darwin 25.3), zsh, most binaries via mise / homebrew / cargo.
- **Source palette (16 colors):** background `#1b182c`, foreground `#cbe3e7`, gray `#a6b3cc`, black `#100e23`, red `#ff8080`, dark_red `#ff5458`, green `#95ffa4`, dark_green `#62d196`, yellow `#ffe9aa`, dark_yellow `#ffb378`, blue `#91ddff`, dark_blue `#65b2ff`, magenta `#c991e1`, dark_magenta `#906cff`, cyan `#aaffe4`, dark_cyan `#63f2f1`.
- **Pre-existing themes (kept side-by-side, not overwritten):** lsd was on Cyberpunk; starship on a Dracula-ish "rainbow" palette; btop on Default. Zellij and Claude Code had no active custom themes. fzf had no color config (`FZF_DEFAULT_OPTS` only had layout flags).

## Decisions

### Cross-tool consistency rules
- **Signature accent: `dark_magenta #906cff`** — used as primary brand color in every tool (starship `accent`, GoLand focus rings, Claude Code `claude` token, btop `cpu_box` and `process` gradient, Slack active-channel pill, Obsidian `--interactive-accent`, fzf `prompt`/`spinner`).
- **Hover variant: `magenta #c991e1`** — paired everywhere as the lighter accent for hover/shimmer states (also used as fzf `pointer`).
- **Inverse text on accent: palette black `#100e23`** — not foreground, since dark-on-bright reads dramatically better than light-on-bright at small sizes (used in Slack active-item text, Obsidian `--text-on-accent`, Claude Code `inverseText`, GoLand default-button fg).
- **Selection / mid-tone surface: derived `#3b3470`** — palette has no native selection color, so we picked the value commonly used by ChallengerDeep's terminal/Vim themes. Same value used everywhere for consistency (lsd `bg+`, fzf `bg+`/`border`/`separator`/`scrollbar`, GoLand selection, Obsidian borders, starship `box`/`current_line`).
- **Elevated surface: derived `#2a2640`** — between bg and selection for hovers, popups, elevated panels.
- **Dim text: derived `#5a5475`** — inactive items where palette gray `#a6b3cc` is too bright (used in fzf `disabled`, Claude Code `subtle`, Obsidian `--text-faint`, GoLand `LINE_NUMBERS_COLOR`).

### Gradient strategy (btop, GoLand, Claude Code rainbow)
- **Severity ramps** (where high = bad): green → yellow → red. Used for CPU load, temperature, memory used, error severity.
- **Color-family ramps** (purely aesthetic, not severity): single-hue brightness ramps. Used for free memory, cached, available, network up/down, process gradient.

### Tool-specific design
- **lsd:** uses RGB arrays `[r,g,b]` — lsd's deserializer accepts named-color strings, single u8, or 3-element array, but **not** `#rrggbb` strings. Schema has `deny_unknown_fields` and `file_type` is `#[serde(skip)]`, so including a `file-type:` block crashes the parse — file-type colors come from `LS_COLORS`.
- **Zellij:** simple 16-color form with hex strings; the newer multilayer styled form (`text_unselected`, `ribbon_*`) is supported but overkill.
- **Starship:** added `[palettes.challengerdeep]` block alongside the existing `rainbow` palette; user flipped `palette = 'challengerdeep'` themselves mid-session.
- **GoLand:** delivered both standalone `.icls` and packaged plugin JAR. `.icls` uses `parent_scheme="Darcula"` so unhandled tokens fall back. Plugin JAR contains the `.theme.json` (294 UI keys), the color scheme as `.xml` (bundled schemes drop the `.icls` extension), and `META-INF/plugin.xml`.
- **Slack:** only themes the sidebar; the message panel/composer is uncontrollable. Theme is just an 8-color comma-separated string pasted into preferences.
- **Obsidian:** dark-only theme. Switching app to light mode falls back to default light rather than half-implementing a washed-out variant.
- **Claude Code:** verified custom theme support via claude-code-guide agent — `~/.claude/themes/<slug>.json` with `name`/`base`/`overrides`. Live reload, no restart needed.
- **fzf:** delivered as a sourceable shell snippet at `~/.config/themes/fzf-challengerdeep.sh` that appends `--color=...` to existing `FZF_DEFAULT_OPTS` rather than replacing it. Used `bg=-1` / `gutter=-1` / `preview-bg=-1` (terminal-default / transparent) since the terminal scheme is already ChallengerDeep.

### Gotcha: shell quoting bug in the fzf snippet
- First draft used `\` line continuations **inside** a single-quoted string. Single quotes preserve everything literally, so the `\` and the newline became part of the value. fzf failed with `invalid color specification` because it saw literal newlines in the `--color=` value.
- Fix: use shell string-concatenation pattern — close the single quote, then `\` newline, then reopen on the next line: `'foo,'\` `'bar:#abc'`. Each adjacent quoted string concatenates into one logical value, but the line continuations are *outside* the strings where they actually mean continuation.
- Worth remembering for any future multi-line shell variable.

## Task State

### Completed — files written and validated
| Tool | Path | Validation |
|------|------|------------|
| lsd | `~/.config/lsd/colors-challengerdeep.yaml` | parses under lsd 1.2.0 (swapped, ran `lsd`, restored) |
| Zellij | `~/.config/zellij/themes/challengerdeep.kdl` + `~/.config/zellij/config.kdl` | parses under zellij 0.40.1; **active** (no prior theme) |
| Starship | `~/.config/starship.toml` (added `[palettes.challengerdeep]` block) | parses under starship 1.19.0; user **flipped to active** |
| btop | `~/.config/btop/themes/challengerdeep.theme` | 42/42 keys, zero diff vs canonical schema |
| Slack | `~/.config/themes/slack-challengerdeep.txt` (reference + the 8-color string) | string ready to paste |
| Obsidian | `~/.config/themes/obsidian-challengerdeep/{manifest.json,theme.css}` | 125 CSS vars, balanced braces |
| Obsidian (deployed) | `~/Documents/obsidian/{home,docs}/.obsidian/themes/Challenger Deep/` | dropped into both active vaults |
| GoLand `.icls` | `~/Library/Application Support/JetBrains/GoLand2024.3/colors/ChallengerDeep.icls` | 24 editor + 103 syntax keys, valid XML |
| GoLand plugin | `~/Downloads/ChallengerDeep.jar` | plugin.xml + theme.json + bundled scheme; 294 UI keys |
| Claude Code | `~/.claude/themes/challengerdeep.json` | 55 token overrides, 24 unique colors, all valid hex |
| **fzf** | `~/.config/themes/fzf-challengerdeep.sh` | parsed cleanly under fzf 0.54.0 via filter-mode test (exit 0) |

### Activated this session
- Zellij (config.kdl + theme dropped, active by default since no prior config)
- Starship (user flipped `palette = 'challengerdeep'` themselves)

### Pending user activation
- **lsd:** `\cp ~/.config/lsd/colors.yaml ~/.config/lsd/colors-cyberpunk.yaml && \cp ~/.config/lsd/colors-challengerdeep.yaml ~/.config/lsd/colors.yaml`
- **btop:** `o` → Theme → `challengerdeep`, OR edit `color_theme = "challengerdeep"` in `~/.config/btop/btop.conf`
- **Slack:** Preferences → Themes → Create new theme → paste `#1b182c,#3b3470,#906cff,#100e23,#2a2640,#cbe3e7,#62d196,#ff5458`
- **Obsidian:** in each vault, Settings → Appearance → Themes → Manage → Challenger Deep → Use
- **GoLand `.icls`:** Settings → Editor → Color Scheme → ChallengerDeep
- **GoLand plugin:** Settings → Plugins → ⚙ → Install Plugin from Disk → `~/Downloads/ChallengerDeep.jar`
- **Claude Code:** `/theme` → scroll past presets → Challenger Deep
- **fzf:** add `. ~/.config/themes/fzf-challengerdeep.sh` to `~/.zshrc` *after* the existing `FZF_DEFAULT_OPTS` export (line 159), then `source ~/.zshrc` or open new shell

## Open Questions
- **GoLand UI plugin** validates structurally (XML/JSON parse, palette references resolve, 294 UI keys covered) but was not launch-tested — the IDE silently falls back to platform defaults for any missing/wrong key. There are 800+ possible UI keys; ~290 covered. Surfaces that may still look Darcula-ish are unknown until run.
- **Obsidian dormant vault** (`~/Documents/notes/`, last touched 2024-05-30) was deliberately skipped. If revived, copy theme dir from `~/.config/themes/obsidian-challengerdeep/`.
- Whether to also produce a matching **`LS_COLORS`** string so file-type coloring in `lsd` matches the same palette (offered, user did not request).
- **fzf-tab integration**: user has the `fzf-tab` zsh plugin in their plugin list. fzf-tab inherits `FZF_DEFAULT_OPTS` so the theme should apply to completion menus too, but not verified live.

## Next Steps
1. Activate the pending themes in each tool (list above) and live-test.
2. **GoLand plugin live test**: install the `.jar`, restart, eyeball the UI. Report any surfaces that still look Darcula-ish (specifically: tool windows, kebab menus, version control sidebar, debug panel, file diff gutter) and the missing keys can be added.
3. If the user wants the dormant `notes` vault themed too: `\cp -r ~/.config/themes/obsidian-challengerdeep ~/Documents/notes/.obsidian/themes/Challenger\ Deep`
4. Optional follow-on: matching `LS_COLORS` for file-type coloring in lsd.
5. Optional follow-on: tweak any specific surface that doesn't read well in practice — palette swaps are localized in each theme file (the design is consistent enough that "tweak the accent" or "darken the box surface" is a one-line edit per tool).

## Reference: canonical source paths
- Re-deployable Obsidian bundle: `~/.config/themes/obsidian-challengerdeep/`
- Slack theme string + slot mapping: `~/.config/themes/slack-challengerdeep.txt`
- fzf shell snippet: `~/.config/themes/fzf-challengerdeep.sh`
- Plugin JAR (re-installable): `~/Downloads/ChallengerDeep.jar`
- All other themes live where the tools expect them; no separate canonical source.


Updated the same note at `Claude/themes/2026-05-04-challenger-deep-port.md`. Now reflects ten tools (added fzf), captures the shell-quoting bug as a future-self warning, and bumps fzf-tab integration to the open-questions list since the plugin should inherit `FZF_DEFAULT_OPTS` but wasn't live-tested.
