How It Works
The Web Content Accessibility Guidelines (WCAG 2.1) require sufficient visual contrast between text and background elements. Level AA is the baseline standard for regulatory compliance, while Level AAA represents top-tier accessibility.
Luminance and contrast ratios are evaluated using the standard W3C relative luminance algorithm.
