Meet WCAG contrast ratios for text and non-text, never rely on color alone, and verify with tools including in dark mode. Use when choosing colors for UI or auditing readability.
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 contrast Sufficient contrast between text and background is what makes an interface readable for users with low vision, color blindness, or just a sunlit screen. It is one of the most common accessibility failures and one of the most checkable: the WCAG ratios are specific numbers you can verify. ## Method 1. **Meet the WCAG text-contrast ratios.** Normal text needs at least 4.5:1 against its background (AA); large text (18pt+, or 14pt+ bold) needs 3:1. AAA raises these to 7:1 and 4.5:1. These are measurable ratios, not opinions: check every text/background pair against them, including text over images and gradients (where contrast varies across the text: the hardest case). 2. **Do not rely on color alone to convey information.** Color-blind users (about 8% of men) cannot distinguish red-error from green-success if color is the only signal: pair color with an icon, text, pattern, or shape (a red X and a green check, not just red and green: see the error-signaling in accessible-forms). "Click the green button" and "required fields are red" fail without a second channel. 3. **Meet non-text contrast too.** UI components and …

How to install
mdr add amey-thakur/ai-skills/color-contrast@sha256:b43aee515ce32583The line at the top of this page pins the label git:20260728.fac4544, 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.
