A common use case for this library is extracting a single color from an image. Here's how to do that:

Learn about the M3 color system.
The library is built out 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 — ex. MDC doesn’t need quantization/scoring/image extraction
- Turns a wallpaper into N colors
- Celebi, which runs Wu, then WSMeans
- Rank colors for suitability for theming
- Quantize buckets a wallpaper into 128 colors
- Enables deduplicating and ranking that output.
- Mapping from roles, i.e. names like primary, to colors.
- Tonal Palette — range of colors that varies only in tone
- Core Palette — set of tonal palettes needed to create Material color schemes
- Hue, chroma, tone
- A new color space based on CAM16 x L*
- Accounts for viewing conditions
- Color interpolation in HCT
- Harmonizing, animations, gradients
- Color — conversions between color spaces needed to implement HCT/CAM16
- Math — functions for ex. ensuring hue is between 0 and 360, clamping, etc.
The Material Theme Builder Figma plugin is recommended for design workflows. It 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.
