Claude Themes

A marketplace of UI themes for Claude, built from established palettes rather than ad hoc color picks. Each theme family is a separate plugin — install only the ones you want.

Installation

Browse and install from the marketplace UI:

/plugin

Or install a family directly:

/plugin install <family>@matcra587/claude-themes

Each plugin's README lists its specific themes and their base values.

ANSI variants

Every family ships each theme in two forms: a regular variant that uses the palette's RGB values, and an (ANSI) variant that delegates code-block syntax highlighting to your terminal's ANSI palette. The reason both exist:

Claude Code lets custom themes override UI chrome (message backgrounds, borders, status indicators, etc.), but syntax highlighting in code blocks is not overridable. Claude selects one of three hardcoded syntax palettes based on the theme's base value:

• base contains "ansi" → syntax highlighting uses the terminal's ANSI palette
• otherwise base contains "dark" → a hardcoded Monokai-style palette
• otherwise → a hardcoded GitHub-light palette

The regular variants use base: "dark" or base: "light", so code blocks get the Monokai-style or GitHub-light syntax palette. That looks fine but is unrelated to the theme family — a Catppuccin Mocha theme still renders Monokai-style syntax in code blocks.

The (ANSI) variants set base: "dark-ansi" or base: "light-ansi", flipping code-block syntax over to the terminal's own ANSI palette. If your terminal is themed to match (e.g. terminal uses Catppuccin Mocha ANSI colors + Claude set to Catppuccin Mocha (ANSI)), Claude's UI chrome and code-block syntax render from one unified palette.

When to use which

• Regular variants — when you want themed Claude UI and don't mind Claude's default code-block colors.
• (ANSI) variants — when your terminal's ANSI palette already matches the theme family. Use these to unify UI and syntax colors under one palette.

Content-wise, all (ANSI) variants share the same ANSI mapping and differ only in which built-in base name they declare.

Theme schema

Each theme is a JSON file in its plugin's themes/ directory and follows the standard Claude theme schema:

{
  "name": "Catppuccin Mocha",
  "base": "dark",
  "overrides": {
    "text": "rgb(205,214,244)",
    "bashBorder": "rgb(243,139,168)"
  }
}

[!NOTE] Some themes intentionally use sparse semantic overrides. If a Claude theme slot does not map cleanly to a source palette color, it is left to Claude's fallback behavior instead of guessing.
