Color contrast is one of the most critical aspects of web accessibility. Poor contrast makes text unreadable for millions of users with low vision or color blindness. WCAG 2.1 requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text.

Tips for web design

Test both your primary text color and secondary/muted text against all background colors used on your site

Check contrast in dark mode too — many sites pass in light mode but fail in dark mode

Don't forget to test link colors, placeholder text, and disabled states — these are commonly missed

Aim for AAA compliance (7:1 ratio) when possible, not just the minimum AA standard
