# Colors
This skill builds and audits color systems. It generates ramps, maps their steps to roles and token names, converts notation and measures rendered contrast pairs.
Never report a contrast value you did not measure, and never estimate a color you could compute. Notation, a tinted neutral and a gradient's interpolation space are project choices, not findings. A broken role mapping, a failing pair and an out-of-gamut step are findings. Perceived lightness throughout means OKLCH `L`, from `0` to `1`.
Whether a pair is required to pass belongs to `better-accessibility`. Surfaces, shadows and icon color belong to `better-ui`.
## Match the project's color system
Reuse the project's tokens and notation. A consistent hex system beats hex with `oklch()` scattered through it.
For a new system, `oklch()` is the best default, because its numbers behave the way the ramp rules below describe. Everywhere else, a color library produces the same ramp in the project's own notation ([color-formats.md](color-formats.md)).
