Prizma
Videos
The Prizma Color system was a color motion picture process, 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.

Color motion picture film refers both to unexposed color photographic film in a format suitable for use in a motion picture camera, and to finished motion picture film, ready for use in a projector, which bears images in color.

A strip of undeveloped 35 mm color negative.
A representation of the layers within a piece of developed color 35 mm negative film. When developed, the dye couplers in the blue-, green-, and red-sensitive layers turn the exposed silver halide crystals to their complementary colors (yellow, magenta, and cyan). The film is made up of (A) Clear protective topcoat, (B) UV filter, (C) "Fast" blue layer, (D) "Slow" blue layer, (E) Yellow filter to cut all blue light from passing through to (F) "Fast" green layer, (G) "Slow" green layer, (H) Inter (subbing) layer, (I) "Fast" red layer, (J) "Slow" red layer, (K) Clear triacetate base, and (L) Antihalation (rem-jet) backing.
