For a Multicolor film, a scene is shot with a normal camera capable of bipacking film. Two black-and-white35mm film negatives are threaded bipack in the camera. One records the color red (via a dyed panchromatic film), and the other, blue (orthochromatic). In printing, duplitized stock is exposed and processed with one record on each side. In a tank of toning solution, the film is floated upon the top of the solution with the appropriate chemical. The cyan record is toned a complementary red with a copper ferrocyanide solution, and the red being toned blue/cyan with ferric ferrocyanide solution.
A sequence in Hell's Angels (1930) was filmed in Multicolor, but printed by Technicolor, as Multicolor could not yet supply as large a demand of printings in such a short amount of time. Multicolor was also utilized in several cartoons of the era.
A 15-second, behind-the-scenes clip in Multicolor of the Marx Brothers filmed on the set of Animal Crackers (1930) exists as part of a Cinecolor short subject entitled Wonderland of California. The first feature filmed entirely in Multicolor was The Hawk (1931), which was re-released five years later in Cinecolor as Phantom of Santa Fe. In 1932, the next (and final) all Multicolor feature, Tex Takes A Holiday (1932), was released.
