materialpaletter

Materialpaletter is a software tool and library that assists designers and developers in creating color palettes compatible with Google's Material Design guidelines. It emphasizes translating base colors into cohesive primary, secondary, and supporting color sets while preserving readability and visual harmony across light and dark modes.

Key features include automatic generation of light and dark variants, consistent shade ramps, and built-in accessibility checks that evaluate contrast against WCAG recommendations. The tool supports color token creation (for example, primary, on-primary, surface, and error tokens) and can adapt palettes for different brand strengths.

Materialpaletter provides multiple export paths: CSS custom properties for web projects, JSON design tokens for design systems, Android XML color resources, and iOS color assets. It is available as a web application, a Node.js library, and a command-line interface, allowing integration into both design pipelines and development workflows.

Usage typically involves selecting or supplying a base color, choosing a palette style, and generating corresponding tokens and variants. Users can preview palettes in a live UI and export them to their preferred format to feed into design systems or codebases.

The project originated as an open-source initiative with community contributions and aims to streamline cross-platform theming while aligning with Material Design principles. It is maintained through community discussions, documentation, and periodic updates. See also Material Design, color tokens, and design systems.
