The diffuse finish is the part of the material that will be most affected by
the light sources. Although the real problem is that lights don't fade with
distance, so each has equal intensity for all distances (if all begin
equal). The following might look okay.

light_source {<-10,10,-10>, color Red fade_distance 8 fade_power 2}
light_source {<0,10,-15>, color Green fade_distance 8 fade_power 2}
light_source {<+10,10,-10>, color Blue fade_distance 8 fade_power 2}

Spotlights would work even better, that way you have more precise control
where the colors go.
