Color Accessibility
Ensuring color choices meet minimum contrast standards so content is readable by users with color vision deficiencies. WCAG AA requires a 4.5:1 contrast ratio for normal text.
About 8% of men and 0.5% of women have some form of color vision deficiency. A palette that looks beautiful but fails contrast checks excludes real users and loses real revenue. The fix is not avoiding color. It is making sure information is never conveyed by color alone and that text meets WCAG contrast ratios. Tools like Stark and the built-in Chrome accessibility auditor catch these issues before they ship.
