Accessibility & Contrast FAQ

Q.What is WCAG 2.1?

WCAG (Web Content Accessibility Guidelines) is the international standard for web accessibility. It defines three levels of conformance: A (lowest), AA (mid-range), and AAA (highest). Most modern websites aim for AA compliance.

Q.What is a good contrast ratio?

For normal text, WCAG AA requires a ratio of at least 4.5:1. For large text (18pt+), the requirement is 3:1. We recommend aiming for 7:1 (AAA) for critical reading content.

Q.Why does my blue button fail on white?

Pure blue on white often has a lower ratio than expected. Try using our Color Picker to find a slightly darker shade that passes the test.

Q.Does this check color blindness?

This tool checks contrast. To see how your colors look to color-blind users, use the 'Simulate' feature in our Visualizer Mode.
