About Color Contrast

Color contrast is a critical component of web accessibility, ensuring that text and interactive elements are readable for all users.

WCAG Contrast Guidelines

  • AA Level (minimum): Requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text
  • AAA Level (enhanced): Requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text
  • Large Text: Defined as text that is at least 18pt (24px) or 14pt (18.7px) and bold

Why Color Contrast Matters

  • Improves readability for all users, especially in varying lighting conditions
  • Essential for users with low vision or color vision deficiencies
  • Required for legal compliance in many jurisdictions
  • Creates a more professional and polished design
