Color Contrast Guide

Understanding and implementing proper color contrast is crucial for creating accessible web content. This guide will help you ensure your designs meet WCAG standards.

What is Color Contrast?
Color contrast refers to the difference in light between foreground (usually text) and background colors. Sufficient contrast ensures that text is readable for all users, including those with visual impairments.
WCAG Contrast Requirements
The Web Content Accessibility Guidelines (WCAG) define specific contrast ratios for different types of content:
  • Normal Text: Contrast ratio of at least 4.5:1
  • Large Text (18pt+ or 14pt+ bold): Contrast ratio of at least 3:1
  • UI Components and Graphical Objects: Contrast ratio of at least 3:1

Tips for Maintaining Good Contrast
  • Use dark text on light backgrounds or light text on dark backgrounds
  • Avoid placing text on busy backgrounds or images
  • Consider using our Color Palette Generator for accessible color schemes
  • Test your designs in grayscale to ensure sufficient contrast
  • Remember that thin fonts may require higher contrast ratios
Common Misconceptions
  • High contrast doesn't always mean black and white
  • Meeting contrast requirements doesn't guarantee overall readability
  • Logos and decorative elements don't need to meet contrast requirements, but consider their visibility
