1. A structure comprising:
an optical element disposed on a surface of an article, wherein the surface of the article includes a base surface and a second surface, wherein the second surface has a first vertical height relative to the base surface, wherein the first vertical height is at least 0.5 millimeter,
wherein the optical element includes a first section disposed on the base surface of the article and a second section disposed on the second surface of the article, wherein the first section of the optical element imparts a first structural color to the base surface of the article, wherein the second section of the optical element imparts a second structural color to the second surface of the article, and wherein the first structural color and the second structural color differ from each other when viewed from the same angle of observation by a person having 20/20 visual acuity and normal color vision from a distance of about 1 meter from the article under the same lighting conditions,
wherein the optical element comprises at least one constituent layer, wherein the number of constituent layer(s) of the first section and the second section are the same, and wherein a thickness of at least one of the constituent layers of the first section is different from a thickness of the corresponding constituent layer of the second section.
