Check WCAG 2.1 accessibility compliance

About 8% of men and 0.5% of women have some form of color vision deficiency. Low contrast makes text hard to read — especially at small sizes, on poor displays, and for users with visual impairments. WCAG (Web Content Accessibility Guidelines) sets minimum values that are legally required in many countries (EU EN 301 549, US ADA, BITV).
Level AA requires 4.5:1 for normal text (below 24 px or 18.66 px bold) and 3:1 for large text. Level AAA requires 7:1 for normal text and 4.5:1 for large text. UI components and graphics need at least 3:1. These values are based on the relative luminance per WCAG formula — hue does not matter.
