A substantially colorless polymeric multilayered film comprising at least 2 surfaces and most of the light ray in the ultrared light zone of the refractive spetrum with most of the light ray in the visible light zone of the perspective spectrum including at least a multi-alternate layer of physically transparent polymeric material of at least 2 types with the optical thickness varying between 0.09um and 0.45um and the ultrared light ray of different refraction rates of the polymeric material for the layers refracting spectrum; and elements in connection with the film for shading of any visible color refracted from the layer impeding any refraction of sensible colors from the film as sensed by human eyes.
