💡 WCAG Quick Reference

  • AA (4.5:1): minimum for normal text — required by most accessibility laws
  • AAA (7:1): enhanced standard — recommended for critical content
  • Large text: 18px+ regular or 14px+ bold — lower threshold (3:1 for AA)
  • UI components: focus indicators, icons — only need 3:1 regardless of size
  • Decorative elements: logos, disabled controls — exempt from contrast requirements
