GdkRGBA

A gdk.rgba.RGBA is used to represent a color, in a way that is compatible with cairo’s notion of color.

gdk.rgba.RGBA is a convenient way to pass colors around. It’s based on cairo’s way to deal with colors and mirrors its behavior. All values are in the range from 0.0 to 1.0 inclusive. So the color (0.0, 0.0, 0.0, 0.0) represents transparent black and (1.0, 1.0, 1.0, 1.0) is opaque white. Other values will be clamped to this range when drawing.
