About this tool
Compare two hex colors and report a WCAG-style contrast ratio for text vs background (AA/AAA hints).
It does not certify your whole site. Font size, weight, and non-text contrast have extra rules. Use it as a fast check while you pick a palette.
Runs in the browser with no account. Pair with HEX to RGB if you need channel values.
Measure WCAG contrast between foreground and background colors for accessibility.
