Frequently Asked Questions

What are WCAG levels?
AA minimum: 4.5:1 normal text, 3:1 large. AAA enhanced: 7:1 normal, 4.5:1 large. Large text = 18pt+ (24px+) or 14pt+ bold (18.66px+ bold).
Why not just trust your eyes?
Humans vary in color perception. WCAG ratios are objective. Gray on white might look fine on your monitor but fail accessibility for users with low vision, older screens, or bright environments.
Auto-fix respects brand?
Our suggester preserves hue and only adjusts lightness. You keep your brand palette's character while gaining accessibility.
