The tool shows the contrast ratio and whether it passes WCAG AA (4.5:1 for normal text) and AAA (7:1 for normal text) standards.
If the contrast fails, adjust either color until you achieve the required ratio. The tool suggests similar colors that pass.

Open WCAG Contrast CheckerWCAG AA requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (18px+ or 14px bold).
AA is the standard level (4.5:1 for text). AAA is enhanced (7:1 for text). Most websites aim for AA compliance as a minimum.
Good color contrast ensures that text is readable for people with visual impairments, including color blindness. It is also required by accessibility laws in many countries.
