Color Operations
Practical color knowledge for developers and designers. Covers color spaces, accessibility, palette generation, CSS implementation, and design token architecture.
Inspired by meodai/skill.color-expert - a comprehensive 286K-word color science knowledge base with 113 reference files. This is a lightweight operational skill for everyday frontend and design work. For deep color science (spectral mixing, historical color theory, CAM16, pigment physics), install the full skill.
Color Space Decision Table
Pick the right space for the task. This is the single most impactful color decision you'll make.
| Task | Use | Why |
|---|---|---|
| Perceptual color manipulation | OKLCH | Best uniformity for lightness, chroma, hue |
| CSS gradients & palettes | OKLCH or color-mix(in oklab) |
No mid-gradient grey/brown deadzone |
| Gamut-aware color picking | OKHSL / OKHSV | Cylindrical like HSL but perceptually grounded |
| Normalized saturation (0-100%) | HSLuv | CIELUV chroma normalized per hue/lightness |
| Print workflows | CIELAB D50 | ICC standard illuminant |
| Screen workflows | OKLAB | D65 standard, perceptually uniform |
| Color difference (precision) | CIEDE2000 | Gold standard perceptual distance metric |
