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

Cheat sheet
Components
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
Quantize
- Turns a wallpaper into N colors
- Celebi, which runs Wu, then WSMeans
Score
- Rank colors for suitability for theming
- Quantize buckets a wallpaper into 128 colors
- Enables deduplicating and ranking that output.
Scheme
- Mapping from roles, i.e. names like primary, to colors.
Palettes
- Tonal Palette — range of colors that varies only in tone
- Core Palette — set of tonal palettes needed to create Material color schemes
HCT
- Hue, chroma, tone
- A new color space based on CAM16 x L*
- Accounts for viewing conditions
Blend
- Color interpolation in HCT
- Harmonizing, animations, gradients
Utils
- Color — conversions between color spaces needed to implement HCT/CAM16
- Math — functions for ex. ensuring hue is between 0 and 360, clamping, etc.

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.
