About Coolors

Coolors lets users generate random harmonious palettes with a single spacebar press, then lock individual colors and regenerate the rest for rapid exploration. The platform includes tools for extracting palettes from images, checking contrast ratios for accessibility compliance, and creating gradient generators. Designers can export palettes in numerous formats including CSS variables, SCSS, JSON, and Adobe Swatch files. The iOS and Android apps bring palette generation to mobile, while integrations with Figma and Adobe allow direct palette import into design workflows. The community library contains millions of user-submitted palettes searchable by color, mood, or keyword.
