Cinecolor

Cinecolor was an early subtractive color-model two color motion picture process, based upon the Prizma system of the 1910s and 1920s and the Multicolor system of the late 1920s and 1930s. It was developed by William T. Crispinel and Alan M. Gundelfinger, and its various formats were in use from 1932 to 1955.
