1. A method comprising:
disposing at least two layers of a constituent layer onto a surface of a polymeric layer of an article to form a first stack, wherein the polymeric layer has a minimum percent transmittance of 30 percent, under a given illumination condition at a first observation angle of about −15 to 180 degrees in the wavelength range of 380 to 740 nanometers;
disposing an intermediate reflective layer onto the first stack, wherein the intermediate reflective layer has a first side surface adjacent the first stack and a second side surface on the side opposite the first side surface, wherein the intermediate layer has a minimum percent reflectance, under a given illumination condition at a first observation angle of about −15 to 180 degrees of about 60 percent or more in the wavelength range of 380 to 740 nanometers, a maximum percent transmittance, under the given illumination condition at the first observation angle of about −15 to 180 degrees of 30 percent or less in the wavelength range of 380 to 740 nanometers, or both, wherein the first stack has 3 to 20 layers, wherein each layer of the first stack are substantially flat; and
disposing at least two layers of the constituent layer onto the second side surface of the intermediate layer to form a second stack, wherein the second stack has 3 to 20 layers, wherein each layer of the second stack are substantially flat, wherein the first stack, the intermediate reflective layer and the second stack comprise an optical element; and
wherein the first stack of the optical element imparts a first structural color to the article from a first side of the optical element, wherein the second stack of the optical element imparts a second structural color to the article from a second side of the article.
