What KColor is
KColor is a free AI color palette generator for creating, refining, and applying color systems. Describe a palette in natural language for branding, websites, user interfaces, marketing assets, or other creative projects. Its previewer places palettes on website and app layouts, letting you assess contrast, hierarchy, accessibility, and visual balance. Accessibility tools include WCAG and APCA contrast checks plus a color-blindness simulator. You can extract colors from an uploaded image; KColor says dropped files are not stored. Palette outputs include SCSS, CSS, Tailwind, Bootstrap, Radix, JSON, CSV, PNG, SVG, ASE, and values such as HEX, OKLCH, HSL, RGB, and Display-P3. You can pin palettes without an account, but saving them requires one. The site also links to a Chrome extension and Figma plugin, and offers an MCP server for Claude that supports palette generation and search, contrast checks, analysis, and color conversion. Its homepage displays a daily limit for Ask Jak sessions, which reset after 24 hours.
