The
Prizma Color system was a technique of color
motion picture photography, invented in 1913 by William Van Doren Kelley and Charles Raleigh. Initially, it was a two-color
additive color system, similar to its predecessor,
Kinemacolor. However, Kelley eventually transformed Prizma into a
bi-pack color system that itself became the predecessor for future color processes such as
Multicolor and
Cinecolor.
