ux-color

Design or critique a product's color palette and system — base hue, harmony, neutrals, semantic colors, tonal scales, and tokens. Applies the always-true core and gates context-dependent decisions (dark mode, brand expressiveness, accessibility trade-offs). Trigger when creating a color palette, choosing UI colors, building a color system, setting up color tokens, or reviewing a palette for issues.

# Color Palette & System Skill


## How this skill behaves (read first)

This is a **generative** skill. Color has two opposite default failure modes: **arbitrary** (pick a nice blue, no system, fails contrast) and **garish** (apply every emotional/cultural association and standout trick → the over-colored "Willy Wonka" palette `aesthetics` warns about). So this skill gates:

1. **Establish brand, audience, and market** — these drive the *one* set of hue/emotion/culture choices worth making.
2. **Apply the always-true core** — a restrained, role-based, tokenized, accessible palette holds for any product.
3. **Make the expressive choices deliberately** — surface base-hue/emotion/saturation/dark-mode as gated decisions, not defaults.

Then **hand off to the audits**: `accessibility` owns contrast ratios and color-blindness; `aesthetics` owns harmony and balance.
