For the color film, try a music supply shop. They have these plastic filters that turn light different colors.
A vinyl sticker/sign shop has translucent color that will stick on in any shade of color you could want. They can just cut you off a small piece for less than a buck or perhaps free if they have some scrap laying around. Small pieces could be had from me too for a small fee of course.
