WCAG Standards Explained
The Contrast Checker is designed to help you ensure that your website's text and images have sufficient contrast to meet the Web Content Accessibility Guidelines (WCAG) standards. WCAG is a set of guidelines that ensure websites are accessible to people with disabilities.

Industry Standard
