Sky Camouflage of Naval Airplanes

The brightness of the light from the sun, sky and sea are analyzed to bring out the principles of day sky camouflage of air planes. Rules are formulated, Chapter III, section 3, which in simplest form are: paint upper surfaces with a dark gray blue; paint underneath surfaces, vertical surfaces, protuberances, with a light gray blue; all paint should be matte. Specific directions for painting the plane and experiments are outlines, in Chapter IV. It is pointed out, Chapter V, that translucent fabric offers greater possibilities of low visibility camouflage than can be achieved by painting opaque fabric.
