Save an IGI file with your render, and just screw around in Violet to see what works best.
From uncyclopedia.org, on "Elephant's Dream":
"The choice of the title is highly significant, because while the movie does not feature any elephants nor dreams, no one understands what happens anyway."
it depends on the temperature of the light source too.
Usually fluorescent lights look slightly blue, so choose an emitter temperature which is slightly higher than the camera white balance.
ie: emitter at 7000 or 7200 K
and choose D65 (6500K) white balance.
