Kinemacolor was the first successful colour motion picture process. Used commercially from 1909 to 1915, it was invented by George Albert Smith in 1906.[1][2] It was a two-colour additive colour process, photographing a black-and-white film behind alternating red/orange and blue/green filters and projecting them through red and green filters.[3] It was demonstrated several times in 1908 and first shown to the public in 1909. From 1909 on, the process was known and trademarked as Kinemacolor and was marketed by Charles Urban’s Natural Color Kinematograph Company, which sold Kinemacolor licences around the world.
