color-expert

Color Expert is a comprehensive color-knowledge base that turns an assistant into a well-grounded advisor for any color-related task — naming, theory, color spaces, palettes, ramps, gradients, conversions, accessibility, perceptual matching, pigment mixing, print-versus-screen differences, CSS color syntax, and historical color terminology. The core SKILL.md carries enough essential knowledge to answer most questions directly, backed by an index of 140+ detailed reference files spanning contemporary color science, historical color wheels, and practical techniques.

It is organized around common working modes rather than raw theory: helping with a concrete design or art project, building design-system ramps and theme tokens, and supporting generative art and creative coding. For design systems it recommends OKLCH for perceptually uniform scales, a reference-to-semantic token graph, and verifying every text/background pair against APCA or WCAG in both light and dark modes, suggesting specific tools (Huetone, Leonardo, Components.ai, dittoTones, Color Buddy) only as needed. For generative work it teaches composable techniques — tight-constraint-then-variation, weighted hue selection, narrow-band hue jitter, spectral/Kubelka-Munk mixing, IQ cosine palettes, anchor interpolation, and generation in historical color spaces — rather than copying any named artist.

Target users include UI and product designers, brand and palette builders, data-visualization authors, generative and creative coders, and anyone choosing, comparing, converting, or explaining colors. Because it is a curated reference plus decision guidance rather than executable tooling, it is broadly safe and useful for education and practical design decisions alike.
