10. The article of claim 1, 2 or 3, wherein the at least one reflector layer is made of a material selected from metals or metal oxides, wherein the at least two component layers are independently made of a material selected from metals or metal oxides.

11. The method of claim 1, 2, or 3, wherein the optical element is a single layer reflector, a single layer filter, a multilayer reflector, or a multilayer filter.

12. The method of claim 9, wherein the base reflective layer has a thickness of at least 10 nanometers, wherein the at least two component layers adjacent to the base reflective layer have different refractive indices, wherein each component layer of the multilayer reflector has a thickness of approximately one-quarter wavelength of a wavelength to be reflected.

Background

Structural color is caused by the physical interaction of light with micro-or nano-features of surfaces and bulk materials, in contrast to the color resulting from the presence of dyes or pigments that absorb or reflect light of a particular wavelength based on the chemical nature of the dye or pigment. Color from dyes and pigments can be problematic in many respects. For example, dyes and pigments and their related chemicals used in the manufacture and incorporation into finished products may not be environmentally friendly.
