What problem does it solve? Color work is full of misleading heuristics: HSL lightness that doesn't match perception, hue-first harmony rules that fail in practice, and naive RGB mixing that turns paint simulations into gray mush. This Skill gives the agent a curated color science knowledge base so it answers color questions with accurate theory, the right color space, and the right tool instead of folk design advice. ## Core Features & Use Cases - Color space guidance: Decision tables for when to use OKLCH, OKLAB, HSLuv, CAM16, CIELAB, or Kubelka-Munk, with corrections to common HSL misconceptions. - Accessibility and palette analysis: WCAG vs APCA contrast statistics, character-first harmony principles, and recommendations for palette generation and linting tools like RampenSau, Poline, and Color Buddy. - Deep reference library: 140+ indexed reference files covering historical color science (Ostwald, Munsell, Ridgway), contemporary research (OKLAB, CIECAM02), and practical techniques (Spectral.js, Culori, pigment mixing). - Use Case: A developer building a design-token system asks for a perceptually even warning-color ramp with accessible text colors; the Skill directs the agent to OKLCH ramps, semantic token layering, and APCA contrast verification. ## Quick Start Ask the agent to recommend a color space and generate an accessible 10-step palette for your UI, and the color-expert skill will activate automatically.
