Accessibility matters.

Check your colors before you start designing.
Select a foreground and a background color. The WCAG chart will show if the combo is accessible.

Poor contrast makes text difficult to read, especially for people with visual impairments. Ensuring proper color contrast helps your designs meet accessibility standards (WCAG) and creates a better experience for all users.

This tool is provided as a quick reference. While it uses WCAG 2.2 guidelines, it does not replace full accessibility testing. Always validate your designs with real users/testers and professional audits.

WCAG 2.2 Contrast Requirements
  • Normal text: Minimum 4.5:1 contrast ratio
  • Large text (≥ 18pt / 24px, or ≥ 14pt / 18px bold): Minimum 3:1
  • Non-essential text (decorative, hidden, or logos): Exempt
AA vs AAA

AA = baseline accessibility (meets most users’ needs).
AAA = enhanced accessibility, maximum readability, but harder to achieve.
