Dark mode example

Dark mode has become increasingly popular, but it’s crucial to ensure it’s implemented accessibly. This article covers the key considerations for creating an accessible dark mode experience.

Why Dark Mode Matters for Accessibility

Dark mode isn’t just about aesthetics—it can significantly improve the experience for users with certain visual conditions and those working in low-light environments.

Key Implementation Considerations

1. Maintain Sufficient Contrast

Even in dark mode, text must meet WCAG contrast requirements:

  • Normal text: 4.5:1 ratio minimum
  • Large text: 3:1 ratio minimum

2. Respect User Preferences

Always respect the user’s system-level dark mode preference:

@media (prefers-color-scheme: dark) {
  /* Dark mode styles */
}

3. Provide Manual Toggle

Give users control over their experience with a manual toggle option.

Best Practices

  • Test contrast ratios in both light and dark modes
  • Ensure all interactive elements remain visible
  • Consider users with color vision deficiencies
  • Provide smooth transitions between modes
