WCAG Color Contrast Checker
Check colour contrast ratio against WCAG AA and AAA accessibility standards
Sample text preview
WCAG contrast requirements ensure text and UI elements are readable for people with low vision. AA standard requires 4.5:1 for normal text and 3:1 for large text.
💡
Tip: Never rely solely on colour to convey information - use patterns, labels, or icons alongside colour for full accessibility.
