Palette Lab

Palette Lab is a free online color toolkit that turns any seed color into a full design palette: generate color harmonies, verify WCAG contrast ratios, and export production-ready CSS, Tailwind, or JSON tokens — all in your browser, no sign-up.

Contrast checker

Set a text color and a background color — or tap T / B on any swatch — and get the WCAG ratio with AA / AAA verdicts.

Harmonies are computed on the HSL hue wheel; contrast follows the WCAG 2.x relative-luminance formula. Nothing leaves your browser — no uploads, no tracking.
