g
Floating-point value specifying the green component of a color. This value generally is in the range from 0.0 through 1.0, with 0.0 being black.
b
Floating-point value specifying the blue component of a color. This value generally is in the range from 0.0 through 1.0, with 0.0 being black.

Remarks

You can set the members of this structure to values outside the range of 0 through 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 that actually remove light from a scene.
