What Colorfool is
Colorfool is a free web tool for generating, checking, previewing, and exporting color palettes. Its generator supports color harmony schemes, locking individual colors, and changing lightness and saturation. Accessibility checks include WCAG contrast ratios and colorblind simulation on every palette, with no paywalled accessibility checks listed. Users can preview palettes applied to a hero, dashboard, buttons, and a form, then export in formats including CSS, SCSS, Tailwind, Figma/Tokens, JSON, Sketch, CMYK, PNG, ASE, .sketchpalette, .swatches, and PPTX. Its AI generator starts from a mood, theme, or object description and accepts conversational refinements. An image scanner extracts a palette in the browser; the site says the image is never uploaded. A separate scanner accepts an image or live website URL. Colorfool can also create a one-page brand guide with color roles, accessible pairings, and usage notes for printing or saving as PDF. The tools are presented for solo users and teams handing off a shared brand system.

Verdict
