Accessible Color Pair Generator

Enter a background, choose a 3:1, 4.5:1, or 7:1 contrast target, and get copy-ready light and dark text candidates.

—These are sRGB contrast candidates. WCAG contrast is only one accessibility requirement; type size, state cues, focus, and non-color indicators still matter.

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.

How to use the Accessible Color Pair Generator

Enter a background and choose a contrast target. The browser searches lightness candidates and returns copy-ready text colors that meet the selected sRGB contrast ratio.

What the result means

4.5:1 is the WCAG AA threshold for typical normal text and 7:1 is the AAA normal-text threshold. Contrast alone does not guarantee an accessible interface.
