    Check color contrast

    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

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of colord, so you can see the experience inside your AI.

It does not authenticate your account with colord. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions colord owners ask.

  • 01

    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.

  • 02

    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.

  • 03

    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.
