Descripción

An Unreal Engine plugin that wraps Google's Material Color Utilities C++ library, exposing the full Material Design 3 dynamic color system to Blueprint and C++.

The third-party library is built as a static library with no external dependencies (Abseil is removed), so it integrates cleanly into the UE build pipeline with no additional setup.

Features

  • Dynamic color scheme generation -- produce a complete set of 54 Material Design 3 color roles from a single seed color.

  • 9 scheme variants -- Tonal Spot, Neutral, Vibrant, Expressive, Fidelity, Content, Rainbow, Fruit Salad, and Monochrome.

  • Light and dark mode -- toggle bIsDark to generate a dark-mode scheme.

  • WCAG contrast adjustment -- tune contrast level from -1.0 to 1.0.

  • Color Scheme data asset (UMCUColorScheme) -- configure seed color, variant, and contrast in the editor; the resolved scheme updates live.

  • Editor detail customization -- visual palette preview directly in the Details panel for scheme data assets.

  • Tonal palette sampling -- sample any tone (0--100) from a seed color's HCT palette, or retrieve the standard 11-stop tone swatch.

  • Color harmonization -- shift a design color's hue toward a key color for visual harmony.

  • Contrast utilities -- compute WCAG contrast ratio between two colors, or find the lightest/darkest color that meets a target contrast ratio.

  • Dislike filtering -- detect colors in commonly disliked hue/chroma ranges and auto-correct them.

  • HCT decomposition and construction -- convert between FLinearColor and HCT (Hue, Chroma, Tone) components.

  • Full Blueprint support -- every function is BlueprintCallable with tooltips and categorized nodes.

Planned

Generate scheme from texture (extract dominant color via quantization)

Batch scheme generation for multiple seed colors
