Another material is theatrical color media. Brands include Rosco Labs & Lee Color Filters. No problem with heat - it is designed to go in front of 1000w lighting instruments so you can even use it in incandescent fixtures. It is available in hundreds of colors, including frosts, which can be used to soften the light as well as adjust the color. There are even colored frosts. It comes in 20" X 22" sheets for around $8.00 per sheet from most theatrical suppliers.
