Values specifying the red, green, blue, and alpha components of a color. These values generally range from 0 to 1, with 0 being black.

Remarks

You can set the members of this type to values outside the range of 0 to 1 to implement some unusual effects. Values greater than 1 produce strong lights that tend to wash out a scene. Negative values produce dark lights, which actually remove light from a scene. For more information, see Colored Lights.
