What this skill does
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 Stability AI Generate reference palettes, test color harmony visually --- Quick Reference Perceptual Color Spaces Why LAB/LCH Instead of RGB? RGB/HSV are device-dependent, not perceptually uniform LAB Euclidean distance ≈ perceived color difference LCH separates Hue (color wheel position) from Chroma (saturation) CIEDE2000 is the gold-standard perceptual distance metric: Correlates with human perception (r > 0.95) Use colormath or skimage.color.deltaEciede2000 → Full details: /references/perceptual-color-spaces.md --- OKLCH: The Modern Standard (2026+) OKLCH has replaced hex/HSL as the professional color standard. …
