This color footage was filmed even before movies had sound, and 13 years before a color feature film was released.
George Eastman House is the repository for many of the early tests made by the Eastman Kodak Company of their various motion picture film stocks and color processes. The Two-Color Kodachrome Process was an attempt to bring natural lifelike colors to the screen through the photochemical method in a subtractive color system. First tests on the Two-Color Kodachrome Process were begun in late 1914. Shot with a dual-lens camera, the process recorded filtered images on black/white negative stock, then made black/white separation positives. The final prints were actually produced by bleaching and tanning a double-coated duplicate negative (made from the positive separations), then dyeing the emulsion green/blue on one side and red on the other. Combined they created a rather ethereal palette of hues."(via Nag on the Lake)
