Color Converter & Contrast Checker
One color in — HEX, RGB, HSL, HSV out — plus the WCAG contrast ratio against a second color, all in your browser.
sRGB only · HSL/HSV are re-expressions of the same color, not other color spaces
Enter both colors to see the contrast ratio.
No color yet.
Accepts #hex (3/4/6/8 digits), rgb()/rgba(), and hsl()/hsla(). Channels outside CSS ranges (like rgb(300, 0, 0)) are refused rather than clamped into a different color. Named CSS colors are not parsed — the names dictionary is a plugin this tool deliberately does not load. Round trips through HSL/HSV can shift the last digit: colord converts through floating-point channels.
