Nord Theme for Aider

A carefully crafted dark theme for Aider that applies the popular Nord color palette, providing a soothing visual experience with cool blues and muted tones optimized for long coding sessions.

What This Does

This skill configures Aider's color scheme using Nord-inspired colors across all interface elements - from user input to AI responses, error messages to completion menus. The theme creates a cohesive, low-contrast environment that reduces eye strain while maintaining clear visual hierarchy.

Instructions

1. **Locate your Aider configuration file**

- Default location: `~/.aider.conf.yml`

- Alternative: `.aider.conf.yml` in your project root (for per-project themes)

2. **Apply the Nord color configuration**

- Copy the color values below into your `.aider.conf.yml` file

- If the file doesn't exist, create it in your home directory

3. **Color assignments**:

- `user-input-color: "#ced4e6"` - Soft blue-gray for your input text

- `tool-error-color: "#ea8f80"` - Muted coral red for errors

- `tool-warning-color: "#c7a84d"` - Warm gold for warnings

- `assistant-output-color: "#52bcce"` - Bright cyan for AI responses

- `completion-menu-color: "#aeb8d4"` - Pale blue for menu text

- `completion-menu-bg-color: "#1c2232"` - Deep navy for menu background

- `completion-menu-current-color: "#f4dbe2"` - Soft pink for selected item text

- `completion-menu-current-bg-color: "#272d41"` - Charcoal blue for selected item background

- `code-theme: "nord-darker"` - Nord-darker syntax theme for code blocks

4. **Restart Aider** to apply the new theme

5. **Verify** the colors appear correctly in your terminal - some terminals may require true color support
