Colour - Film historians have been primarily interested in the introduction of colour film technology as an integral aspect of the film industry and its development, with the move to colour understood, at least in part, as a consequence of the need to differentiate cinema from television in the 1950s (see film history).

Colour film - A film that is in colour; a film that is not black and white. Cinemagoers at the turn of the 20th century would have experienced a vivid mixture of black-and-white and colour cinematography (see early cinema); indeed, a clear distinction between the two was not established until the 1920s. Early colour processes included the hand painting of each frame: this was expensive and time-consuming—a silent film ten minutes in length and running at 16fps (see frames per second) would require 9,600 separate frames to be painted.
