About

Authoring adaptive color palettes for generating color based on a desired contrast ratio. For a detailed walkthrough of Leonardo, check out this article. To make it easier for designers and engineers to leverage color science to create custom interpolations for a value scale, and to make it easier for designers and engineers to conform to WCAG minimum contrast standards by using contrast ratio as the starting point, rather than a post-color-selection auditing process. Leonardo is the open-source project adobe/leonardo (https://github.com/adobe/leonardo) by adobe, released under Apache-2.0. Ion packages it unmodified from commit eb6481da40df, adding only a manifest, an icon and a storage compatibility script.
