## Theme File Format

Each theme is defined in TOML format with the following structure:

```toml
name = "theme-name"

# Text colors
text = "#ffffff"              # Main text color
placeholder = "#808080"       # Placeholder/muted text

# Background colors
background = "#000000"        # Main background
command_bar_background = "#111111"
status_background = "#111111"

# Border colors
focused_panel_border = "#ff00ff"    # Active panel border
unfocused_panel_border = "#800080"  # Inactive panel border

# Message role colors
user_message_role = "#00ffff"       # User messages
assistant_message_role = "#ffff00"  # Assistant messages
thinking_panel_title = "#ff00ff"    # Thinking panel title

# Mode indicator colors (status bar)
mode_normal = "#00ffff"
mode_editing = "#00ff00"
mode_model_selection = "#ffff00"
mode_provider_selection = "#00ffff"
mode_help = "#ff00ff"
mode_visual = "#ff0080"
mode_command = "#ffff00"

# Selection and cursor
selection_bg = "#0000ff"      # Selection background
selection_fg = "#ffffff"      # Selection foreground
cursor = "#ff0080"            # Cursor color

# Status colors
error = "#ff0000"             # Error messages
info = "#00ff00"              # Info/success messages
```

## Color Format

Colors can be specified in two formats:

1. **Hex RGB**: `#rrggbb` (e.g., `#ff0000` for red, `#ff8800` for orange)
2. **Named colors** (case-insensitive):
   - **Basic**: `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, `white`
   - **Gray variants**: `gray`, `grey`, `darkgray`, `darkgrey`
   - **Light variants**: `lightred`, `lightgreen`, `lightyellow`, `lightblue`, `lightmagenta`, `lightcyan`

**Note**: For colors not in the named list (like orange, purple, brown), use hex RGB format.

OWLEN will display an error message on startup if a custom theme has invalid colors.

## Creating Custom Themes

To create your own theme:

1. Copy one of these files to `~/.config/owlen/themes/`
2. Rename and modify the colors
3. Set `theme = "your-theme-name"` in `~/.config/owlen/config.toml`
4. Or use `:theme your-theme-name` in OWLEN to switch

## Embedding in Binary

These theme files are embedded into the OWLEN binary at compile time using Rust's `include_str!()` macro. This ensures they're always available, even if the files are deleted from disk.

Custom themes placed in `~/.config/owlen/themes/` will override built-in themes with the same name.
