Colorfool
What it is
Colorfool is a web-based color palette tool for creating, checking, previewing, and exporting palettes. Its generator supports color harmony schemes, locking individual colors, and adjusting lightness and saturation. It can check WCAG contrast ratios and simulate colorblindness on every palette; the free plan includes these checks. Preview colors in examples showing a hero, dashboard, buttons, and a form. The AI generator accepts a mood, theme, or object description and can refine results through conversation. An image scanner extracts colors in the browser, and the site says the image is not uploaded; a separate scanner accepts an image or live website URL. Colorfool can also create a one-page style guide with color roles, accessible pairings, and usage notes for printing or PDF saving. Export choices include CSS, SCSS, Tailwind, Figma/Tokens, JSON, Sketch, CMYK, PNG, ASE, .sketchpalette, .swatches, and PPTX. The .swatches format is best-effort because Procreate has no published specification. The free plan is listed as free.
