Enter colors above, then audit to check them against the background color.
Confirming one text and background color pair passes WCAG is useful, but auditing an entire palette or a live page for every contrast failure and getting an actual suggested fix for each one is a different job entirely, closer to a compliance review than a single spot check. This tool audits color contrast ratios against WCAG 2.1 AA and AAA requirements and suggests an actual fix for each failure, proposing an adjusted color that would pass rather than only reporting which pairs don't.

Useful for auditing an entire palette or a page's color combinations at once instead of testing one pair at a time, getting a concrete suggested color adjustment instead of just a failing ratio number, or running a full accessibility compliance pass before a design system ships.
