A color (red, green, blue, and alpha).
Pure red with maximum brightness corresponds to (red = 65535, green = 0, blue = 0). Similarly for pure green and pure blue of maximum brightness.
Pure white corresponds to (red = 65535, green = 65535, blue = 65535).
Pure black corresponds to (red = 0, green = 0, blue = 0).
Opacity can also be set with the alpha selector on a color; for more information, see Compound Variables.
