Color.fromPalette()

static Color fromPalette( Variant value , Variant palette = nullvar )

Parameters

value The value to get a color for.
palette The Color Palette to get a color from.

Returns

Color The resulting color.

Description

Returns a color from a color palette.

A palette can either be specified by name or by node. The color palette will look up the color assigned to the given value, asserting a color for the value if necessary. However, if the palette is using a gradient, the palette will linearly interpolate between the color values already defined by the palette. If no palette is specified, then the resulting color will be generated using the given value.
