Thanks to thstone for the advice!
I used full color led's, some resistors, and a microswitch to do this.
I can choose from 5 colors as of now, and could get the full spectrum by adding a pwm chip. For now, five is plenty.
Colors are blue, green, red, purple, and blue-green(aqua). The pictures didn't show up real well, but I'll post these and get some better ones in the daylight. I think the brightness of the led's combined with the dark interior made my camera's auto exposure go nuts. The focus is terrible as well.
Blue-green didn't look any different from blue in the pictures, but did in person, so I did not include the picture.
