# The snippet appends --color=... to whatever FZF_DEFAULT_OPTS already holds,

# 2. Or copy the FZF_CHALLENGERDEEP_COLORS value below and paste it directly

#
# bg and gutter are -1 (transparent) so the theme inherits your terminal bg —
# replace with #1b182c if you want the theme to be self-contained.
