About Color Contrast & WCAG

What is Color Contrast?

Color contrast refers to the difference in luminance between foreground (text) and background colors. Higher contrast makes text easier to read, especially for people with visual impairments or color blindness.

WCAG Standards

  • WCAG AA (Minimum): 4.5:1 for normal text, 3:1 for large text
  • WCAG AAA (Enhanced): 7:1 for normal text, 4.5:1 for large text
  • Large Text: 18pt (24px) or 14pt (18.5px) bold and larger

Why It Matters

  • Improves readability for all users
  • Essential for users with visual impairments
  • Legal requirement in many jurisdictions
  • Better user experience overall
  • SEO and accessibility benefits

How to Use

  1. Enter or pick your foreground (text) color
  2. Enter or pick your background color
  3. Check the contrast ratio and compliance results
  4. Adjust colors if needed to meet standards
  5. Use the preview to see how it looks

Tips for Better Contrast

  • Use dark text on light backgrounds or vice versa
  • Avoid low-contrast color combinations (e.g., gray on gray)
  • Test with actual content, not just sample text
  • Consider colorblind users - don't rely on color alone
  • Use tools like this to verify your designs
