This directory implements the cross-platform Color Pipeline machinery, including all core classes and the //ui-level mixers/recipes. Embedders may add more mixers/recipes to define additional colors or modify how these appear (for an example in Chrome, see the chrome/browser/ui/color/ directory).
To the greatest degree possible, colors in Chromium should be identified using ColorIds and their physical values obtained from an appropriate ColorProvider; direct use of SkColor outside ColorRecipes should be limited to colors which are necessarily transient, e.g. colors based on a current animation state or colors sampled dynamically from playing media.
