Leonardo: an open source contrast-based color generator

• An in-depth article about leonardocolor.io, a tool that helps you to find colour palettes that conform to the WCAG AA contrast guidelines. It explains the different interpolation algorithms in more detail than I was able to digest, but the really intriguing idea is one of using the NPM module to generate accessible palettes in real time, dynamically in your web app, allowing users to adjust the brightness and contrast of your site’s theme colours to suit their vision. See the demo.
