Color Contrast Accessibility for Product Interfaces

Color contrast affects whether people can comfortably read text, especially in bright light, low-quality displays, or visual impairment contexts.

Check body text first

Small text needs stronger contrast than large display text. Start with navigation, buttons, labels, and form fields.

Test real states

Hover, disabled, selected, and error states all need enough contrast. A palette that works in one state may fail in another.

Pair design with measurement

Visual taste matters, but contrast ratios give teams a shared baseline for accessibility decisions.
