FlexPaletteType enum

Enum used to select tones included in produced FlexTonalPalette.

When using type FlexPaletteType.common the chroma of high tones, >= 90, is limited to maximum 40. This keeps the chromacity of tones 90 to 100, lower than 40. If the source color use more chromacity than 40, there may be a sudden jump in chroma reduction at tone 90. This is the standard behavior for the original Material 3 tonal palette computation. The FlexPaletteType.common is intended to be used when there is a need to follow strict M3's original palette design.

When using the FlexPaletteType.extended type tones, there are not only the new tones, but the chroma limit of tones >= 90 is also removed. This increases fidelity of higher tone when high chromacity is used.

Values

common → const FlexPaletteType

Default common tones consisting of the 15 tones originally used in FlexSeedScheme.

Original Material 3 color system included 13 tones 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 95, 99, 100.

FlexSeedScheme includes tones 5 and 98 in addition to these tones in its definition of common tones.

extended → const FlexPaletteType

Extended tones used in Material 3 revision for additional fidelity in surface colors. These were added during 1st half of 2023 to the Material 3 color system specification.

The added tones 4, 6, 12, 17, 22 are for new dark mode surfaces in revised Material 3 dark surface colors. Likewise added tones 96, 94, 92, 87 are for light mode surfaces in the updated Material 3 color system. For more information, see: https://m3.material.io/styles/color/the-color-system/color-roles
