Just to add to what Wolf said... you could take three instruments with color scrollers, pack them in tight together and aim them carefully to hit the same space as close as possible and create a form of RGB type of mixing.
However, the gel in the scroller is actually subtractive. You are taking white light, subtracting everything but red, green, and blue in each instrument, then trying to put them back together to make white... that's nuts. (Just as nuts as taking a bunch of white LED's and filtering them to create Red when Red LED's will do the job so much better.)
In the end, LED's are best suited for RGB additive color mixing while Incandescent/Discharge instruments are best suited for CMY subtractive color.
Is this making sense?
