About

ColorBox is a color toolkit for designers and developers: pick colors from images, analyze color properties, check WCAG contrast, convert between RGB/HEX/HSL, mix CMYK, and generate gradients and palettes. Preview and export results, simulate color blindness, apply variants, lock tones, and iterate quickly with Regenerate.

A calm, spacious interface emphasizes whitespace, hierarchy, and order. It offers light/dark themes, multilingual support, and runs across web, mobile, and desktop.
