Palette Tools
Leonardo is a sophisticated color system tool developed by Adobe for creating, managing, and sharing accessible color systems at scale. It provides fine-grained control over contrast ratios and color ramp construction, making it one of the most capable free tools available for building design system color tokens that meet accessibility standards. The open-source model allows teams to integrate it into their own tooling and token generation pipelines.
