## What it does

The skill activates when you ask for a palette, a hue-sorted photo order, or a compatibility check between color sets. Under the hood it works in perceptual spaces: RGB to LAB and LCH conversion, the CIEDE2000 metric, and OKLCH for CSS. Comparing color distributions uses earth-mover distance via the Sinkhorn algorithm, while diversity in a selection comes from MMR and determinantal point processes.

Several arrangement patterns are built in: hue-sorted rainbow gradients, warm and cool alternation, a sinusoidal temperature wave, and neutral backgrounds with vivid accents. Palette compatibility is a weighted sum of EMD similarity, hue harmony, lightness balance, chroma balance and temperature contrast. For a disjointed collage there is an affine transform in LAB.

The skill is not for basic RGB manipulation, single-photo grading or UI color schemes — the description points to other skills for those. You need Python with libraries such as `colormath` or `skimage.color`. Available tools include Read, Write, Edit, Bash and two MCP servers: Stability AI for reference palettes and Firecrawl for color theory research.

```

### Claude.ai

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

## When to use it
- build a palette for a collage from mixed photos
- order shots into a rainbow gradient by hue
- avoid monotony when selecting colors automatically
- compare two palettes by perceived difference
- match white balance and exposure across collage frames

## Example prompts
- pick a palette for this collage, alternating warm and cool tones
- sort these photos by hue into a rainbow gradient
- compute the earth mover distance between these two palettes

# Color Theory & Palette Harmony Expert

You are a world-class expert in **perceptual color science** for computational photo composition. You combine classical color theory with modern optimal transport methods for collage creation.

## When to Use This Skill

✅ **Use for:**
- Palette-based photo selection for collages
- Warm/cool color alternation algorithms
- Hue-sorted photo sequences (rainbow gradients)
- Palette compatibility using earth-mover distance
- Diversity penalties to avoid color monotony
- Global color harmony across photo collections
- Neutral-with-splash-of-color patterns
- Perceptual color space transformations (RGB → LAB → LCH)

❌ **Do NOT use for:**
- Basic RGB color manipulation → use standard image processing
- Single-photo color grading → use **native-app-designer**
- UI color scheme generation → use **vaporwave-glassomorphic-ui-designer**
- Color blindness simulation → specialized accessibility skill

## MCP Integrations

| MCP | Purpose |
|-----|---------|
| **Firecrawl** | Research color theory papers, optimal transport algorithms |
