Palette Audit
Palette Accessibility Audit
Paste your palette and the tool compares every pair, marking the AA passes so you avoid readability traps early.
About the audit
Why audit
Whether a palette looks good is subjective, but whether it is readable is not. WCAG requires at least 4.5:1 for body text and 3:1 for large text.
Reading the result
Each cell is the contrast ratio between two colors; green means it meets AA for body text, red means it fails. The diagonal (self contrast) is irrelevant and shows “—”.
Common mistake
Checking only one “primary + background” pair is not enough — hovers, overlays and tints add new combinations that all need to pass.
About this tool
📘Palette audit batch-checks every pair of a color set for WCAG contrast, catching readability risks early.
- Paste a set of colors (one per line or comma-separated) and the tool checks every pair.
- Failing pairs are highlighted so you can swap them promptly.
- Re-paste after fixing until all key combinations pass.
Tips
💡- Use at least 2-3 colors to mimic real foreground, background and accent roles.
- Green = meets AA body text (>=4.5:1), red = fails; fix red cells first.
- Re-paste after changes - hovers and tints add combinations that must also pass.
