KColor
What it 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, interface design, marketing assets, or other creative projects. A previewer places palettes on website and app layouts, helping you assess contrast, hierarchy, accessibility, and visual balance. The tools include WCAG and APCA contrast checks and a color-blindness simulator. You can also extract colors from an uploaded image; the page says dropped files are not stored. Palette outputs include CSS, SCSS, Tailwind, Bootstrap, Radix, JSON, CSV, PNG, SVG, ASE, and values in formats such as HEX, OKLCH, HSL, RGB, and Display-P3. Palettes can be pinned without an account, but saving them requires one. KColor links to a Chrome extension and Figma plugin and provides an MCP server for Claude with palette generation and search, contrast checks, palette analysis, and color conversion. The homepage displays a daily limit for Ask Jak sessions, which reset after 24 hours.
