## What it does

The skill organizes tokens into three layers. Global tokens hold raw palette values, semantic tokens define purpose-driven aliases where theme overrides occur, and component tokens handle scoped styling. This separation keeps components decoupled from hardcoded colors.

The architecture covers color modes, brand variants, and density scales. Never invert colors blindly. The skill guides you to reduce brightness deliberately, use lighter surfaces for elevation, and desaturate dark backgrounds.

If your project requires only a single static palette, this skill is excessive. The author recommends using `color-system` for standalone palettes or `dark-mode-design` for dedicated dark mode styling. Implementation targets CSS custom properties, per-theme token files, and Figma variable modes.

## Requirements
- Works with: Figma

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill theming-system -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/theming-system/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/theming-system/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill theming-system -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/theming-system/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill theming-system -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/theming-system/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills theming-system
```

2. **Manually: put the files in place**
- File: `.github/skills/theming-system/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill theming-system -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path design-systems/skills/theming-system
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/theming-system/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill theming-system -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Owl-Listener/designer-skills/tree/HEAD/design-systems/skills/theming-system/SKILL.md

## When to use it
- Separate global, semantic, and component tokens cleanly
- Configure dark mode without naive color inversion
- Structure multi-brand and white-label theme variants
- Implement density switching between compact and spacious layouts

## Example prompts
- Design a three-layer token architecture supporting light, dark, and high-contrast modes via CSS custom properties.
- Map semantic tokens for a white-label app that needs three distinct brand themes.
- Set up surface elevation rules and desaturated palette tokens for dark mode.

description: Design theming architecture — brand variants, dark mode, and high-contrast — mapped through token layers. Use when one system must serve multiple themes. For a single palette use `color-system` (ui-design); for dark mode craft use `dark-mode-design` (ui-design).

# Theming System
You are an expert in flexible theming architectures for multi-brand, multi-mode design systems.
## What You Do
You design theming systems allowing one component library to support multiple visual themes through token mapping.
## Architecture
- **Layer 1**: Global tokens (raw palette)
- **Layer 2**: Semantic tokens (purpose-driven aliases) — themes override here
- **Layer 3**: Component tokens (scoped)
## Theme Types
- Color modes: light, dark, high contrast, dimmed
- Brand themes: primary, sub-brands, white-label, seasonal
- Density: comfortable, compact, spacious
## Dark Mode Considerations
- Don't just invert — reduce brightness thoughtfully
- Use lighter surfaces for elevation (not shadows)
- Desaturate colors for dark backgrounds
- Test text legibility carefully
- Provide image/illustration variants
## Implementation
CSS custom properties, token files per theme, Figma variable modes, runtime switching.
## Best Practices
- Tokens-first: themes emerge from overrides
- Test every component in every theme
- Respect OS theme preferences
- Document themeable vs fixed tokens
```
