What is WebAIM Contrast Checker?

The WebAIM Contrast Checker tests a foreground and background colour pair and shows whether it passes WCAG 2 contrast requirements for normal text, large text and interface elements. Enter hex values or use the colour pickers, then nudge the lightness sliders until the pair passes.

Pros: what WebAIM Contrast Checker does well

  • Clear pass or fail results
  • Covers text and interface elements
  • Free with no account

Cons: where it falls short

  • Checks one colour pair at a time
  • Does not test whole pages
