Components
The library is composed of multiple components, each with its own folder and tests, each as small as possible.
This enables easy merging and updating of subsets into other libraries, such as Material Design Components, Android System UI, etc. Not all consumers will need every component โ ex. MDC doesnโt need quantization/scoring/image extraction.
| Components | Purpose |
|---|---|
| blend | Interpolate, harmonize, animate, and gradate colors in HCT |
| contrast | Measure contrast, obtain contrastful colors |
| dislike | Check and fix universally disliked colors |
| dynamiccolor | Obtain colors that adjust based on UI state (dark theme, style, preferences, contrast requirements, etc.) |
| hct | A new color space (hue, chrome, tone) based on CAM16 x L*, that accounts for viewing conditions |
| palettes | Tonal palette โ range of colors that varies only in tone Core palette โ set of tonal palettes needed to create Material color schemes |
| quantize | Turn an image into N colors; composed of Celebi, which runs Wu, then WSMeans |
| scheme | Create static and dynamic color schemes from a single color or a core palette |
| score | Rank colors for suitability for theming |
| temperature | Obtain analogous and complementary colors |
| utilities | Color โ convert between color spaces needed to implement HCT/CAM16 Math โ functions for ex. ensuring hue is between 0 and 360, clamping, etc. String - convert between strings and integers |
Background
The Science of Color & Design - Material Design
Design tooling
The Material Theme Builder Figma plugin and web tool are recommended for design workflows. The Material Theme Builder delivers dynamic color to where design is done. Designers can take an existing design, and see what it looks like under different themes, with just a couple clicks.
