Color Math Accessibility
SkillAI & modelsCalculate, review, and generate web color systems using RGB, HSL, LAB, OKLCH, contrast ratios, luminance, opacity, blend modes, and light/dark mode transformations. Use when auditing accessible colors, converting color models, deriving palettes, checking WCAG contrast, building theme tokens, or debugging opacity and CSS blend math.

What this skill tells your AI
The instructions your AI receives, as published by hashgraph-online/awesome-codex-plugins in plugins/LVTD-LLC/skills/skills/color-math-accessibility/SKILL.md and read by Ahel’s review.
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.
