Check color contrast on Color Contrast Checker Alternative
Pass foreground and background colors in any format (HEX, RGB, HSL, CSS name). Returns the exact contrast ratio, WCAG AA/AAA pass/fail for both normal and large text, and a human-readable verdict. AI cannot reliably calculate contrast ratios — this engine uses the official WCAG 2.1 relative luminance formula. Checks WCAG 2.1 color contrast ratio between foreground and background. Returns AA/AAA compliance for normal and large text
What the Color Contrast Checker Alternative MCP Server unlocks
Your agent just picked #6c757d text on a #e9ecef background. Looks fine, right? Wrong — it fails WCAG AA with a 3.9:1 ratio. Your users with low vision can't read it, and your client's accessibility audit just failed.
This MCP uses the official WCAG 2.1 relative luminance formula to calculate the exact contrast ratio between any two colors. No approximation. No hallucination. Just the math that the W3C defined.
The Superpowers
- Full WCAG 2.1 Matrix: AA and AAA compliance checked for both normal text (4.5:1 / 7:1) and large text (3:1 / 4.5:1) simultaneously.
- Any Color Format: Pass HEX, RGB, HSL, or CSS named colors — mix and match freely.
- Human Verdict: Returns 'Excellent (AAA)', 'Good (AA)', 'Large Text Only', or 'Fail' — no ratio tables to memorize.
- Exact Ratio: The precise contrast ratio to 2 decimal places, not a guess.
Frequently asked questions about the Color Contrast Checker Alternative MCP Server
My AI says this color combination passes WCAG. Should I trust it?
No. LLMs cannot reliably calculate relative luminance — they approximate. This engine uses the exact W3C formula: L = 0.2126R + 0.7152G + 0.0722*B with sRGB gamma correction. Trust the math, not the prediction.
What's the difference between AA and AAA levels?
AA requires 4.5:1 contrast for normal text — the legal minimum in most countries. AAA requires 7:1 — the gold standard for maximum readability. Large text (18pt+) has relaxed thresholds: 3:1 for AA, 4.5:1 for AAA.
Can I mix color formats? Like HEX for foreground and a CSS name for background?
Absolutely. Pass '#333333' as foreground and 'white' as background, or 'rgb(0,0,0)' with 'hsl(0,0%,95%)' — the engine normalizes everything internally.
