/ About /

Leonardo is a color tooling platform for UI designers and developers that generates accessible color systems based on target contrast ratios. It supports adaptive themes for dark mode, perceptually balanced color scales across multiple color spaces, and colorblind-safe palette generation. Output options include CSS custom properties, design tokens, SVG exports, and an npm module for end-user personalization.

/ How it works /

Users define target contrast ratios or lightness values, and Leonardo automatically generates color swatches, adaptive themes, and exportable outputs across multiple color spaces.

/ Who it's for /
