Audits and repairs color palettes against WCAG contrast thresholds - 4.5:1 for body text, 3:1 for large text and UI components, 7:1 for AAA - and makes them safe for color-blind users, delivering a verified pairing table. Use when someone asks "does this color pass contrast", "make my brand color accessible", "is this palette color-blind safe", "why did my contrast check fail", or is remediating color findings from an audit. Do NOT use to invent a brand palette from scratch - use…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Color Accessibility A palette that fails contrast ships a product that a measurable slice of users cannot read: low-vision users lose the text, and roughly 8% of men (and about 0.5% of women) with red-green color blindness lose any meaning carried by hue alone. The costly mistake this skill prevents is approving colors that look fine on a designer's bright monitor and fail on real screens, in sunlight, and in audits - forcing a token-system rework after components already reference the broken values. ## Operating procedure Work the steps in order: pairings must be enumerated before ratios are computed, and ratios must pass before color-blindness simulation, because a palette that fails contrast is not worth simulating. ### Step 1: Gather inputs Collect before starting. Label any assumed value as a guess. 1. Brand and functional colors as hex values (primary, semantic red/green/yellow, neutrals). 2. Every background surface they sit on - including dark mode surfaces if one exists. 3. Target conformance: default to WCAG AA. Use AAA (7:1 body, 4.5:1 large) for reading-heavy products, older audiences, or contractual/regulated requirements. …

How to install
mdr add skillmedev/skills/color-accessibility@sha256:d8ee874b4e39e755The line at the top of this page pins the label git:20261005.bea4ea5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
