Web accessibility ensures that everyone, including users with visual impairments, can read your website content. Color contrast is a critical factor.
Understanding WCAG Standards
The Web Content Accessibility Guidelines (WCAG) define two levels of contrast ratios:
- Level AA: Requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text.
- Level AAA: Requires an enhanced contrast ratio of 7:1 for normal text and 4.5:1 for large text.
Testing Color Combinations
Check your background color hex code against your foreground text color. A contrast calculator evaluates the mathematical difference in relative luminance to give you a pass or fail rating instantly.
