Solution

Text must have sufficient contrast with its background for readability. WCAG AA requires 4.5:1 for normal text and 3:1 for large text (18px+ or 14px+ bold). Use tools like WebAIM Contrast Checker to verify. Common issues: light gray text, text over images without overlay. Don’t rely on color alone to convey information - add icons or text labels.
