Palette Accessibility Checker
Check every color pair in your palette against WCAG contrast guidelines.
About this tool
Check every color pair in a palette against WCAG AA and AAA text contrast thresholds. Find failing combinations instantly. Palette Accessibility Checker runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- Palette Accessibility Checker is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
