Étude de la Lumière

A woman brushing her hair; shaping and decorating ceramics; crystal: these and other short subjects show off the color value of these subjects in this sole known movie by Maurice Audibert.

It's not clear which, if any, photographic color system was used to make this. Although the earliest versions of Technicolor had been in commercial use for half a decade by this time, hand coloring and stencil coloring were still in use, Technicolor would continue to evolve into the three-color monopack that would be popular for decades. Other companies tried to compete, but it wasn't until the 1950s that other, cheaper systems became popular.
