Prizma Color
Quick Summary
Prizma Color was an early photographic process that aimed to achieve color in motion pictures. Introduced in 1919, it was initially an additive color system but was later revised. The process utilized a "duplitized" film, meaning it had an emulsion on both sides. One side was treated with a red-orange tone, and the other with a blue-green tone. This subtractive process was one of the first to use a single film strip in a standard projector without the need for filters. Although the Prizma company eventually ceased to exist, the duplitized film stock was used in lower-cost systems as late as the early 1950s.1
