a color% object. An add-color<%> object only exists within a
style-delta% object.

method
r : (box/c (integer-in -1000 1000)) g : (box/c (integer-in -1000 1000)) b : (box/c (integer-in -1000 1000))
Gets all of the additive values.
The r box is filled with the additive value for the red component of the color. The g box is filled with the additive value for the green component of the color. The b box is filled with the additive value for the blue component of the color.
