About Color Contrast Checker Alternative MCP Server
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.
LlamaIndex agents combine Color Contrast Checker Alternative tool responses with indexed documents for comprehensive, grounded answers. Connect 1 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.
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.
