Material Color Tool

This tool generates Material Design color palettes from a base color or seed hues, producing primary, secondary, surface, background, and error swatches that align with Material color tokens. It evaluates contrast against text and UI elements to support accessible combinations, and offers light and dark variants for theme parity.
Conceptually, the tool maps input colors to a tokenized color system. It applies hue rotation, lightness shifts, and elevation-based tinting to create cohesive swatches. Outputs include hex values, RGB(A), and token names suitable for design tokens, CSS variables, or JSON exports.
Who benefits: product designers, UI engineers, and design-system teams that need consistent branding and accessibility across platforms. Unique value includes direct material-token alignment, automatic contrast checks, and easy export of palettes and tokens for implementation.
Core features and use cases: seed color input; auto-generated palette; contrast validation; light/dark versions; export in JSON, CSS, or YAML; and optional guidance on where to apply each token within interfaces.
