Cam16
CAM16, a color appearance model. Colors are not just defined by their hex code, but rather, a hex code and viewing conditions.
CorePalette
An intermediate concept between the key color for a UI theme, and a full color scheme. 5 tonal palettes are generated, all except one use the same hue as the key color, and all vary in chroma.
FlexCorePalette
An intermediate concept between the key color for a UI theme, and a full color scheme. Five tonal palettes are generated, plus a default error palette if not provided.
FlexTonalPalette
A convenience class for retrieving colors that are constant in hue and chroma, but vary in tone.
FlexTones
Configuration data class that defines which tone to use from each FlexTonalPalette when assigning used color to each ColorScheme color.
Hct
HCT, hue, chroma, and tone. A color system that provides a perceptually accurate color measurement system that can also accurately render what colors will appear as in different lighting environments.
TonalPalette
A convenience class for retrieving colors that are constant in hue and chroma, but vary in tone.
ViewingConditions
In traditional color spaces, a color can be identified solely by the observer's measurement of the color. Color appearance models such as CAM16 also use information about the environment where the color was observed, known as the viewing conditions.

Enums

FlexPaletteType
Enum used to select tones included in produced FlexTonalPalette.
