A color scroller or color changer is an electro-mechanical lighting accessory used in theater, film, dance and concerts to change the color projected by stage lighting instruments without the need of a person to be in the vicinity of the light. A color scroller moves plastic "gel" color gel into the beam of the light. It is generally attached to the gel frame holder at the transmitting end of a lighting fixture, so color is introduced after the beam characteristics have been defined by the optics of the lighting instrument. Most scrollers are controlled via DMX512 protocol, but some newer models (e.g. Wybron's Coloram IT) also utilize the RDM protocol. When color scrollers were first introduced around 1980, a number of companies produced them, including: Avolites, GAM Products, Morpheus Lights, Rainbow, Rosco Laboratories and Wybron Inc. Now the main manufacturers are: A.C. Lighting, Apollo, Morpheus Lights, Rainbow and Wybron (in alphabetical order).
