The first color systems that appeared in motion pictures were additive color systems. Additive color was practical because no special color stock was necessary. Black-and-white film could be processed and used in both filming and projection. The various additive systems entailed the use of color filters on both the movie camera and projector. The first successful subtractive color system began with Kodak's Kodachrome system. Using duplitized film, red and green records were exposed. By bleaching away the silver and replacing it with color dye, a color image was obtained. Kodachrome, however, did not find much use in the commercial market.
