CanDoYa Accessible Palette Generator vs Colorfool

CanDoYa Accessible Palette Generator is a free web and browser-extension tool that turns a brand color and page background into interface color roles. It generates text, muted text, surface, primary, on-primary, accent, and border colors, then checks intended foreground/background pairs against WCAG contrast thresholds. Users choose AA or AAA targets and receive exact ratios with pass or fail results. The generator keeps the chosen hue and saturation where possible, searching lighter or darker variants to meet the selected ratio. Accent colors may use analogous, complementary, or triadic hues and receive the same contrast check. A live interface preview shows the palette in context. Individual HEX values or a complete CSS custom-property block can be copied. Palette generation, contrast measurement, and CSS export run locally in the browser, and entered colors are not uploaded. The free plan allows unlimited palettes without an account or usage limit. Most tools continue working offline after the page loads. The report evaluates opaque sRGB contrast only and does not establish whole-product accessibility.

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.
