What color formats are supported?
HEX (#RRGGBB, #RGB), RGB/RGBA, HSL/HSLA, HSV, and CMYK. All conversions are bidirectional.
What is WCAG contrast checking?
WCAG defines minimum contrast ratios between text and background colors. AA requires 4.5:1 for normal text, 3:1 for large text. AAA requires 7:1 and 4.5:1 respectively.
What is perceived brightness?
A formula that calculates how bright a color appears to the human eye (weighted for human vision sensitivity). Useful for choosing text colors on colored backgrounds.

CMYK is converted using a standard RGB to CMYK formula. Note that true CMYK requires profile-based conversion for print accuracy.
