About Colour Contrast Checker

Check the contrast between different colour combinations against WCAG standards

Compare the contrast ratio of two colours, background and foreground, on any webpage against the WCAG 2 AA and AAA levels for normal and large text.

More information about understanding colour contrast: https://webaim.org/articles/contrast/

Features

  • Enter colours as hex codes or colour names, or adjust them with RGB and HSL sliders
  • Pick colours straight off the webpage with the eyedropper
  • Save up to 5 colour combinations (stored locally) to refer back to later
  • Reverse background and foreground colours
  • Copy a colour to the clipboard, or generate a share link for the pair

After installing, reload any tab that was already open before the extension can run on it. On pages where extensions cannot run (browser settings, the Web Store) the icon shows a short message instead.

Data source

Covers every Chrome Web Store extension with at least 100 users, found through the store's public sitemap. User counts are read from public listing pages. The 10% most-used extensions are refreshed daily, the next 40% weekly and the next 40% monthly; the least-used 10% are not refreshed. Google displays rounded user counts (and caps the display at 10,000,000+), so small changes may not be visible. Rating counts above 1,000 are rounded (e.g. 1.6K).
