Color
Build perceptually coherent color systems in OKLCH — palettes, ramps, semantic tokens, dark/light theme families, and contrast discipline. Use this skill whenever choosing ANY colors for visual work: UI themes, brand palettes, data-visualization series colors, game graphics, generative art, slides, or syntax themes. Trigger on requests like "pick colors", "make a palette", "add dark mode", "this…

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Color
Color decisions in this package are made in OKLCH (perceptual lightness L, chroma C, hue H), not hex or HSL, because equal numeric steps in OKLCH are equal perceived steps — which is what makes ramps even, themes coherent, and contrast predictable. Hex is only an output format.
Workflow
- Read the design philosophy (from
design-direction); the palette's emotional
register comes from there, not from this skill.
- Construct the palette in OKLCH using
[references/palette-construction.md](references/palette-construction.md) — anchor hue → neutral ramp (tinted, never pure grey) → accent ramp → semantic colors.
- If the work has themes, build dark and light as **sibling palettes, not
inversions**, per [references/themes.md](references/themes.md).
- Verify every text/background pair against
[references/contrast-and-restraint.md](references/contrast-and-restraint.md) before shipping; it also covers when glow/saturation is earned vs. noise.
Which reference to load
| Situation | Load | |---|---| | OKLCH mechanics, converting, browser/tool support | references/oklch-foundations.md | | Building a palette, ramps, data-viz series colors | references/palette-construction.md | | Dark mode, theme families, elevation in dark UIs | references/themes.md | | Contrast checking, WCAG/APCA, glow & saturation discipline | references/contrast-and-restraint.md |
Non-negotiables
- Body text meets WCAG AA (4.5:1) minimum; UI chrome ≥ 3:1. Check, don't eyeball.
- Neutrals carry a trace of the anchor hue (C ≈ 0.005–0.02). Pure grey reads dead.
- One color is the loudest in any view. If two compete, demote one.
- Never ship a palette without rendering it in the real artifact and running the
critique skill on the result.
