About 1 in 12 men and 1 in 200 women have some form of color vision deficiency. Designing accessible UIs ensures your charts, buttons, alerts, and other UI elements are distinguishable regardless of color perception.
WCAG 2.1 guideline 1.4.1 states that color must not be the only visual means of conveying information. Always use additional cues like icons, labels, or patterns alongside color to communicate meaning.
