DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.118

Custom Theme Creation and Management

What

Users can now create, edit, and manage custom color themes with fine-grained color token overrides.

Details
  • Custom themes are stored as JSON files in the user's themes directory (~/.claude/themes/)
  • Each theme specifies a name, base theme (dark or light), and color overrides
  • Color overrides accept rgb(r,g,b), #rrggbb, ansi256(n), or ansi:name formats
  • Custom themes appear in the /theme picker with a (custom) label
  • A "New custom theme…" option is available in the theme selector to create themes interactively
  • File watcher auto-reloads themes when JSON files are added, changed, or removed
  • Themes from plugins are also supported via a themes field in plugin.json or a themes/ directory
  • Plugin settings schema adds themesDirectories for specifying additional theme paths
Evidence

Theme creation flow (search for "__new_custom_theme__") and color validation (search for "Accepts rgb(r,g,b)" and "rgb(r,g,b) · #rrggbb · ansi:red").

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
