"How to Make and Operate Moving Pictures" published by Funk and Wagnalls in 1917 notes the following:

OF the many attempts to produce cinematograph pictures... the greatest amount of attention so far has been attracted by a system invented by G. A. Smith, and commercially developed by Charles Urban under the name of "Kinemacolor." In this system (to quote from "Cassell's Cyclopædia of Photography," edited by the editor of this present book), only two colour filters are used in taking the negatives and only two in projecting the positives. The camera resembles the ordinary cinematographic camera except that it runs at twice the speed, taking thirty-two images per second instead of sixteen, and it is fitted with a rotating colour filter in addition to the ordinary shutter. This filter is an aluminium skeleton wheel... having four segments, two open ones, G and H; one filled in with red-dyed gelatine, E F; and the fourth containing green-dyed gelatine, A B. The camera is so geared that exposures are made alternately through the red gelatine and the green gelatine. Panchromatic film is used, and the negative is printed from in the ordinary way, and it will be understood that there is no colour in the film itself.
