WCAG Accessibility Guidelines
Why Contrast Matters
Proper contrast ensures text is readable for everyone, including users with visual impairments, color blindness, or viewing in bright sunlight.
Level AA
Minimum standard for most websites. Requires 4.5:1 for normal text and 3:1 for large text (18px+ or 14px+ bold).
Level AAA
Enhanced standard for better accessibility. Requires 7:1 for normal text and 4.5:1 for large text. Recommended for body content.
Best Practices
- Always test your color combinations
- Use tools to check contrast ratios
- Provide alternative ways to distinguish information
- Test with actual users when possible
Creating Accessible Color Schemes
Follow these steps to create beautiful and accessible color schemes for your projects:
- Start with a base color: Choose your primary brand color or a color that represents your design concept.
- Generate harmonies: Use the Harmonies tab to explore complementary, analogous, and triadic color schemes based on your base color.
- Create variations: Generate shades and tints to build a complete color palette with light and dark variations.
- Check accessibility: Use the Contrast Checker to ensure text remains readable on all backgrounds. Aim for at least AA compliance.
- Extract from inspiration: Upload reference images to extract color palettes and maintain consistency with your inspiration.
- Export and implement: Export your palette as CSS variables, SCSS, or JSON to easily integrate into your project.
