# Color.js OKLCH, Display P3 & Lab Color Engine

Executes color conversions across RGB, Display P3, OKLCH, CIELAB, and HSL using Color.js: color gamuts, Delta E 2000 perceptual distance, WCAG 2.1/3.0 contrast, and smooth gamut mapping.

## When to Invoke
Invoke this skill whenever you need to:
- convert srgb to oklch
- calculate delta e color difference
- map color to display p3 gamut

## Execution SOP & Rules
1. Parse and convert colors cleanly: const color = new Color('#3b82f6').to('oklch').
2. Format modern CSS strings using color.toString({ format: 'oklch' }).
3. Calculate perceptual difference with colorA.deltaE2000(colorB).
4. Ensure colors are mapped into target display gamuts with color.toGamut({ space: 'srgb' }).

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
