What KColor is

KColor is a free color palette generator for creating, refining, and applying color systems on the web or through an extension. Describe a palette in natural language for a brand, website, interface, marketing asset, or creative project. A previewer places palettes on website and app layouts to help assess contrast, hierarchy, accessibility, and visual balance. Accessibility tools include WCAG and APCA contrast checks plus a color-blindness simulator. You can also extract colors from an uploaded image; the page says dropped files are not stored. Exports include CSS, SCSS, Tailwind, Bootstrap, Radix, JSON, CSV, PNG, SVG, and ASE, as well as values such as HEX, OKLCH, HSL, RGB, and Display-P3. Palettes can be pinned without an account, but saving them requires one. KColor also links to a Chrome extension and Figma plugin and offers a public MCP server for Claude, with palette generation and search, contrast checks, analysis, and color conversion. The homepage displays a daily limit for Ask Jak sessions, which reset after 24 hours.
