Frequently asked questions

What color formats are supported?
HEX (#RGB / #RRGGBB / #RRGGBBAA), RGB / RGBA (0-255), HSL / HSLA (0-360°, 0-100%), and HSV / HSVA. Conversions are mathematically exact.
How does the contrast checker work?
It computes the WCAG 2.1 contrast ratio between two colors and checks compliance against AA (4.5:1 normal text, 3:1 large text) and AAA (7:1 normal text, 4.5:1 large text) thresholds. Useful for verifying accessible color combinations.
