Colorfool

Colorfool is a free web-based tool for generating, checking, exporting and previewing color palettes. Its generator supports harmony-aware palettes, color locking, and adjustments to lightness and saturation. It checks WCAG contrast and simulates colorblindness on every palette without paywalled accessibility checks. You can preview colors applied to a hero, dashboard, buttons and form, then export palettes in formats including 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 accepts conversational refinements. An image scanner extracts colors in the browser; the site says the image is not uploaded. A separate scanner accepts an image or live website URL. Colorfool can also produce a one-page brand guide with color roles, accessible pairings and usage notes for printing or PDF saving. Its tools are presented for both solo users and teams handing off a shared brand system.

Colorfool suits people developing a palette who want to check accessibility, preview applications and export files for design workflows. It also offers tools for teams preparing a color handoff to a client or colleagues.

Colorfool brings palette creation, accessibility checks, previews and many export formats together in a free web tool. Its .swatches file is best-effort because Procreate does not publish an official specification.

Overview

Colorfool is a free, web-based color palette generator for creating, checking, exporting and previewing palettes. It combines color-harmony controls with accessibility checks and export tools, so a palette can be explored visually and prepared for use in other workflows. The site presents it for both solo users and teams working on a shared brand system, including handoff to a team or client.

For homeowners and DIY painters, Colorfool is best understood as a colour-planning aid rather than a paint-selection or coating tool. Its palette previews can help explore how colours relate, but the listed features do not identify paint products, specify surface suitability or provide paint-matching guidance. Treat its output as a starting point for choosing colours, not as a substitute for checking a real coating’s finish, coverage or application requirements.

The generator supports both palette methods and image extraction. You can build a palette using harmony schemes, or use the image scanner to extract colours from an image in the browser. The site says the image is never uploaded. A separate scanner page also offers live website URL input for pulling a palette.

Key features

Harmony controls and accessibility

Colorfool describes seven harmony schemes: analogous, complementary, split-complementary, triadic, tetradic, square and monochrome. It also supports color locking and adjustments to lightness and saturation, giving you ways to keep selected colours while refining the rest of a palette.

The site says WCAG contrast ratios and colorblind simulation are free on every palette. These checks are relevant when selecting colours for digital interfaces and shared brand materials. They do not indicate how a paint colour will look in a room, on a particular material or under changing light.

Previewing, generation and guides

A palette preview applies colours to a hero area, dashboard, buttons and a form. This gives the palette a practical visual context, though the examples are interface components rather than painted walls, trim or floors.

The AI palette generator accepts a mood, theme or object description and allows conversational refinements. The style guide generator turns a palette into a one-page brand guide with colour roles, accessible pairings and usage notes; the guide can be printed or saved as a PDF.

Exports and palette management

Export options listed on a palette page include CSS, SCSS, Tailwind, Figma/Tokens, JSON, Sketch, CMYK, PNG, ASE, .sketchpalette, .swatches and PPTX. The site also lists saved palettes, a brand color library and print color support.

There is a qualification for Procreate users: Colorfool says its .swatches export follows a community-documented structure because Procreate does not publish an official specification. The site therefore describes that export as best-effort, not as an official format.

Pricing

Colorfool lists a Free plan at no cost, marked Free forever. The pricing notes say there is no free trial and no paywalled accessibility checks. No paid plan is listed in the provided pricing details.

Platforms

Colorfool is available on the web. Its image scanner extracts a palette in the browser, and the scanner page also accepts a live website URL. The palette can be exported to a range of file formats, including image, print and design-tool formats.

Who it's for

Colorfool may suit DIY painters who want to explore a group of colours before taking ideas to a paint counter or comparing them against samples. Image extraction can help start from a photograph, while harmony controls offer a structured way to vary a palette. The previews are interface-focused, however, so they cannot show how a colour will appear on a home’s walls, woodwork, concrete or other surfaces.

It is also positioned for solo users and teams building a shared brand system. Accessibility checks, a brand color library, saved palettes, style guides and handoff-ready exports support that kind of work. Users preparing a digital palette should choose formats that fit their destination; those considering the Procreate export should keep its stated best-effort status in mind.

Verdict

Colorfool offers a broad set of free palette tools: harmony controls, image extraction, accessibility checks, contextual previews, style guides and numerous export options. That makes it useful for developing and organizing colour ideas, especially where a palette needs to move into a digital design or shared brand workflow. For a home painting project, its role is narrower: use it to explore combinations, then assess candidate colours on the actual surface and confirm product suitability separately.
