The ColorGroup type is used to define a set of colors with certain roles. Although a ColorGroup has no visual appearance, it defines colors used to customize rendered items.
Default values of colors are equal to active group colors of default-constructed
QPalette
.

ColorGroup { alternateBase: "red" base: "green" }
