Kinemacolor was an additive process operated with alternating red and green filters that were applied to the shutter in front of the camera and in front of the projector. With at least 32 fps the frame rate was double the minimal frame rate of 16 fps. Time parallax with small differences between the red and green record resulted in color fringes that became visible when objects or scenes were moving.
“In 1930 Mannes and Godowsky were invited to join the staff of the Kodak Research Laboratory, where they concentrated on methods of processing multilayer films, while their colleagues worked out ways of manufacturing them. The result was the new Kodachrome film, launched in 1935. Three very thin emulsion layers were coated on film base, the emulsions being sensitised with non-wandering dyes to red, green and blue light, the red-sensitive layer being at the bottom.” (Coe, Brian (1978): Colour Photography.
