Natural color was a term used in the beginning of film and later on in the 1920s, and early 1930s as a color film process that actually filmed color images, rather than a color tinted or colorized movie. The first natural color processes were in the 1900s and 1910s and were two color additive color processes or red and green missing primary color blue, one additive process of time was Kinemacolor. By the 1920s, subtractive color was mostly in use with such processes as Technicolor, Prizma and Multicolor, but Multicolor was mostly never in use in the late 1920s, Technicolor was mostly in use. The only one who cared to mess with Multicolor was William Fox, probably because Multicolor was more cheaper of a process and at the time in 1929 William Fox was in debt. The difference between additive color and subtractive color were that an additive color film required a special projector that could project two components of film at the same time, a green record and a red record. But additive color didn't required a special projector, the two pieces of film were chemically formed together and was projected in one strip of film.
