Color Math Accessibility

Use this skill when colors need to be explainable, accessible, and reproducible. It focuses on color math that affects real UI outcomes: contrast, palette relationships, perceptual lightness, opacity, and blending.

Quick Start

1. Read guidelines.md to select the smallest relevant file set.
2. Load references/color-systems/rules.md for implementation decisions.
3. Load references/color-systems/examples.md when editing code.
4. Use workflows/audit-color-system.md for multi-step derivation or debugging.
