Contrast Checker

WCAG 2.1 Level AA (4.5:1 for normal text, 3:1 for large text) and Level AAA (7:1 for normal text, 4.5:1 for large text).

At minimum 4.5:1 for normal text (AA). For maximum accessibility, aim for 7:1 (AAA). Large text (18px+ or 14px bold) needs only 3:1.

Sufficient color contrast ensures text is readable for people with low vision or color blindness, and is required by accessibility laws.
