Color Contrast Checker for Accessibility
Check whether text and background colors are readable enough before publishing UI changes.
Long-tail guide
Who this is for
Designers, developers, indie makers, and content creators who need quick readability checks.
Color contrast is one of the easiest accessibility issues to check early. A quick browser tool can prevent low-contrast buttons, badges, labels, and body text from shipping unnoticed.
Good use cases
Common tasks
- Check a call-to-action button before launch.
- Review dashboard labels and small text.
- Compare brand colors against white or dark backgrounds.
- Fix link colors that are too subtle.
Recommended workflow
- Paste or pick the foreground color.
- Paste or pick the background color.
- Read the contrast result for normal and large text.
- Adjust color values and test interactive states separately.
When not to use it
- Do not treat contrast as a complete accessibility audit.
- Do not test only the default state if hover, disabled, or selected states use different colors.
- Do not rely on visual judgment alone for small text.

FAQ
Does contrast guarantee accessibility?
No. It is a useful signal, but layout, focus, labels, semantics, and keyboard behavior also matter.
Should I check large and normal text separately?
Yes. Different text sizes have different readability expectations.
