-This directory is reserved for future template files and customization resources.
+This directory contains template files for custom color schemes that can be copied to your template installation.
 
-## Custom Color Palettes
+## Custom Color Palette Templates
 
-For custom color schemes, you can create your own CSS files with custom CSS variables:
+Template files are provided for both light and dark themes with complete Bootstrap button definitions:
 
-1. Create a new CSS file in `src/media/css/colors/light/` or `src/media/css/colors/dark/`
-2. Define CSS variables following the pattern in `colors_standard.css`
-3. Use Joomla's template settings (System → Site Templates → MokoCassiopeia → Custom Code tab) to load your custom CSS
+### Available Templates
 
-**Reference**: See [CSS Variables Documentation](../docs/CSS_VARIABLES.md) for complete variable reference.
+| File | Theme | Description |
+|------|-------|-------------|
+| `colors_custom_light.css` | Light | Custom light theme with all Bootstrap button variants |
+| `colors_custom_dark.css` | Dark | Custom dark theme with all Bootstrap button variants |
+
+### Using Custom Color Templates
+
+1. **Copy** the template file to your template's CSS directory:
+   ```bash
+   # For light theme
+   cp templates/colors_custom_light.css src/media/css/colors/light/colors_custom.css
+   
+   # For dark theme
+   cp templates/colors_custom_dark.css src/media/css/colors/dark/colors_custom.css
+   ```
+
+2. **Customize** the CSS variables in your copied file:
+   - Modify `--color-primary`, `--accent-color-primary`, etc. to match your brand
+   - Adjust Bootstrap state colors (`--success`, `--info`, `--warning`, `--danger`)
+   - Update button variants if needed
+
+3. **Register** in `src/joomla.asset.json`:
+   - Ensure `template.light.colors_custom` and `template.dark.colors_custom` assets are defined
+   - Already configured by default in the asset manifest
+
+4. **Activate** via Joomla admin:
+   - Go to System → Site Templates → MokoCassiopeia
+   - Select "Custom" in the Color Palette dropdown
+   - Save and check your site
+

+
+**Solid Buttons:**
+- `.btn-primary`, `.btn-secondary`, `.btn-success`, `.btn-info`, `.btn-warning`, `.btn-danger`, `.btn-light`, `.btn-dark`
