Leonardo is an open source tool for creating adaptive color palettes; a custom color generator for creating colors based on target contrast ratio. Leonardo is delivered as a Javascript module (@adobe/leonardo-contrast-colors) with a web interface to aid in creating your color palette configurations, which can easily be shared with both designers and engineers. Simply put, Leonardo is for dynamic accessibility of your products.
