Design for Everyone

Is your text readable by people with visual impairments? Our Color Contrast Checker measures the contrast ratio between foreground and background colors against WCAG accessibility standards. A legal requirement for government websites and a moral imperative for all designers. Enter any two colors and instantly see if you pass AA (4.5:1 for text) or AAA (7:1 for enhanced) compliance levels.

WCAG Explained

The Web Content Accessibility Guidelines ensure content is perceivable by users with low vision, color blindness, or age-related sight decline. This checker calculates relative luminance and contrast ratios using the official W3C formula. Fail the test? Try lighter backgrounds or darker text until you hit that magic 4.5:1 ratio—your users will thank you!

A11y Fact: About 1 in 12 men and 1 in 200 women have some form of color blindness. Apple and Google mandate strict contrast guidelines for their platforms. Good contrast is just good design!
