What's the difference between AA and AAA?
AA requires normal text contrast ≥4.5:1 and large text ≥3:1. AAA requires normal text ≥7:1 and large text ≥4.5:1. Most sites only need AA.
What color formats are supported?
Supports HEX (#FF0000), RGB (255,0,0), HSL (0,100%,50%) auto-detection, plus common color names (red, blue, etc.).
What qualifies as large text?
WCAG defines large text as ≥18pt or ≥14pt bold. Large text has lower contrast requirements, making compliance easier to achieve.
