"Dr Jumeaux 3 colour film. One of the early attempts to place colour kinematography upon the screen was a 3 colour process invented by Dr Jumeaux of Southwick nr. Brighton, England. This process conceived by Dr Jumeaux in 1898 was experimented upon by him for many years, during which time a considerable sum of money was spent in the endeavour to bring it to commercial perfection. It was founded upon the principle of Ives Chromoscope, using the 3 primary colors, red, yellow and blue, side by side upon a color sensitized film 3 1/4 inch in width, and taken in a camera fitted with 3 lens, behind each of which was a color filter. The negative was developed and a print made in the usual manner and a special projector fitted with 3 color filters and lens was used, the central lens was fixed and the two outside lens were made to swivel until the pictures from all 3 lenses were supersposed upon the screen. The results of this system were never satisfactory, as the angular disparity between the lenses would not allow of a correct superimposition of the objects" (Will Day, 25 000 years to trap a shadow, tapuscrit, archives Cinémathèque française).
