Colorfool vs Gpick

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.

Gpick is a free, open-source color picker and palette editor for Linux. It samples colors from the desktop, with magnification and keyboard control of the pointer, and can assign names to colors automatically. Palette tools let users build palettes from images, generate schemes, mix colors, adjust lightness or saturation, and create harmonious colors. For noisy or patterned sources, oversampling averages multiple pixel values using five falloff types. Gpick imports and exports Inkscape/GIMP palettes and Adobe Swatch Exchange files; export options also include MTL, CSS, HTML, and customizable text files. HTML exports can be shared as palette previews with people who do not use palette software. A floating mode provides a pointer-following window and notification-area icon for basic picking, but excludes palette editing and color adjustment. Command-line arguments let other programs and scripts use Gpick. Downloads include Debian and Ubuntu packages for amd64 and source archives.
