Feature Request: Customizable Terminal Color Theme / UI Styling Support

[tonylan2010tiger-hue]

Problem / Motivation

Currently, Kimi Code CLI only supports a binary theme = "dark" | "light" option. While functional, this is quite limiting for users who:

• Use terminal emulators with custom color palettes (e.g., Catppuccin, Gruvbox, Nord, Dracula, Tokyo Night)
• Have accessibility needs requiring high-contrast or specific color combinations
• Want the CLI interface to blend seamlessly with their overall development environment aesthetic
• Are used to modern CLI tools (like bat, eza, btm, lazygit) that offer rich theming support

Proposed Solution

Introduce a more flexible theming system for Kimi Code CLI. Possible approaches:

1. Built-in Preset Themes

   • Provide a set of popular built-in themes: catppuccin, gruvbox, nord, dracula, tokyo-night, solarized, monokai, etc.
   • Usage: theme = "catppuccin-mocha" in ~/.kimi/config.toml

2. Custom Theme Configuration

   • Allow users to define custom color mappings in the config file:

   [theme.custom]
   background = "#1e1e2e"
   foreground = "#cdd6f4"
   accent = "#89b4fa"
   success = "#a6e3a1"
   error = "#f38ba8"
   warning = "#f9e2af"
   info = "#89dceb"
   border = "#45475a"
   selection = "#313244"

3. Environment Variable / XDG Integration

   • Respect $LS_COLORS, terminal background detection, or integrate with common theme environment variables

4. Theme Marketplace / Community Themes

   • Allow loading themes from ~/.kimi/themes/ directory
   • Community can share themes via GitHub repo or simple file sharing

Benefits

• Improved accessibility for users with visual impairments
• Better integration with modern developer workflows
• Reduced eye strain with cohesive terminal aesthetics
• Community engagement through shared custom themes

Prior Art / Inspiration

• bat — custom theme support via --theme
• eza — color scheme customization
• lazygit — extensive theme configuration
• btm — built-in color themes

Additional Context

Currently the only theming knob is:

theme = "dark"  # or "light"

Would love to see Kimi Code CLI become more visually flexible!
