ColorBox vs Colorfool

ColorBox is a free web tool and extension for creating color systems and accessible palettes. You can adjust multiple colors in one tab and share a system as a URL or JSON file. Contrast indicators show 3:1, 4.5:1, and 7:1 levels for color sets, while HSV and OKLCH provide color-space modes. Auto Dark Mode creates an inverted set from original inputs; duplicated sets can also be edited manually. Hue progression rotates clockwise or counterclockwise. Export options include Config, Output, Tailwind, CSS, OKLCH, and Swift. The maker describes importing systems into Figma through a plugin and JSON, with custom step names and generated Paint Styles. A Sketch route uses that Figma workflow, then SVG export. The color algorithm can be consumed through NPM with exported JSON for code generation. Custom curves were described as unavailable in ColorBox at the cited time. The free plan is ad-free.

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.
