Leonardo

Generates accessible color scales from a target WCAG contrast ratio, not just a hue.

Webfree

Leonardo is a free web application from Adobe for building accessible color palettes. Rather than choosing colors and auditing contrast afterward, users start from a target WCAG contrast ratio and let Leonardo generate a matching color scale, with shareable links that preserve the exact settings. It's built for designers and engineers maintaining design systems.
