Colorfool vs Grabient

Colorfool is a web tool for generating, checking, previewing, and exporting color palettes. Its generator offers harmony-aware palettes, color locking, and controls for lightness and saturation. It describes harmony schemes including analogous, complementary, split-complementary, triadic, tetradic, square, and monochrome. WCAG contrast ratios and colorblind simulation are available on every palette, and the palette preview applies colors to a hero, dashboard, buttons, and a form. Export formats include CSS, SCSS, Tailwind, Figma/Tokens, JSON, Sketch, CMYK, PNG, ASE,.sketchpalette,.swatches, and PPTX. The AI generator takes a mood, theme, or object description and allows conversational refinements. An image scanner extracts colors in the browser; the site says images are not uploaded. A separate scanner accepts an image or live website URL. The style guide generator creates a one-page brand guide with color roles, accessible pairings, and usage notes for printing or saving as PDF. Colorfool is presented for solo users and teams handing off a shared brand system. The free plan is listed at free, with no paywalled accessibility checks.

Grabient is a free web-based tool for making CSS gradients and managing palettes. Users can adjust gradient style, angle and steps, then create, save, browse, manage or like palettes. Search accepts descriptive terms such as colors, moods or themes. Exports include CSS, SVG and PNG; palette pages also offer copy options for colors, ShaderToy and JSON. Unauthenticated GET endpoints provide palette JSON, search, ranked palette lists and PNG renders without an API key. A URL seed determines a palette, so repeating the same seed reproduces its colors. Generated or exported gradients may be used for lawful personal and commercial projects under a perpetual, royalty-free license. Some features require an account, available through Google OAuth or email magic links. The documented API and image reads are limited to 300 requests per 10 seconds per IP, and PNG output has size caps. Grabient recommends itself for UI palettes, gradients and backgrounds, not accessibility contrast checks, image palette extraction, exact brand-hex matching or print/CMYK work.
