About Chroma Palette

Chroma Palette is a small set of free, focused color utilities built for people who work with color every day — designers, developers, and anyone who needs a quick, correct answer without sign-ups or clutter.

How the tools work

Every tool runs entirely in your browser using standard HTML, CSS, and JavaScript. There is no server processing, no account, and no tracking of the colors you enter. The contrast checker implements the WCAG 2.x relative luminance and contrast formulas exactly, so you can trust the pass/fail results.

Why free?

Small utilities like these don't need to be gatekept behind paywalls or buried under ads. We aim to keep the tools fast, private, and accurate, and to cover hosting costs only if and when the site earns the right to show ads (see the Privacy Policy for how that would work).
