Preview palette roles on a UI mockup

Use the first five colors as navigation, primary action, accent, surface, and page background. Rotate roles to test combinations quickly.

—Nav text contrast

—Button text contrast

—Body text contrast

This is a quick visual role preview, not a complete component library or accessibility audit. Real states, focus rings, disabled controls, charts, icons, and semantic status colors still need review.

Connected color workflow

v10.74 keeps the established color/conversion widgets intact while connecting picking, palette generation, contrast review, visual preview, scales and CSS/JSON reuse. Color work stays in the browser, and recent palettes can be stored locally without an account.

Color and accessibility boundaries

HEX/RGB/HSL/HSV/OKLCH conversions are numerical color-model operations. CMYK output is an RGB-derived approximation rather than ICC-profiled print proofing. WCAG contrast ratios measure luminance contrast only and do not certify a full interface. Color-blindness previews are design simulations, not medical tests.
