Design Tips for Accessibility
- Use high contrast between text and background colors
- Don't rely solely on color to convey information
- Add patterns, textures, or labels to distinguish elements
- Test your designs with multiple color vision types
- Use tools like this simulator during design process
- Consider using colorblind-friendly palettes
