1. A structure comprising:
an optical element disposed on a surface of an article, wherein the optical element includes at least a first section disposed on a first area of the article and a second section disposed on a second area of the article, wherein the first section of the optical element imparts a first structural color to the first area of the article, wherein the second section of the optical element imparts a second structural color to the second area of the article, and wherein a color parameter of the first structural color and the second structural color are different from each other when viewed from the same angle of observation of a viewer having 20/20 visual acuity and normal color vision from a distance of about 1 meter from the article;
wherein the optical element comprises at least one layer, wherein the first section has a first number of layers and the second section has a second number of layers, wherein the first number of layers and the second number of layers are different, wherein at least one layer of the first section and a corresponding layer of the second section have a different average thickness,
wherein the first section includes a first set of layers, wherein the second section includes a second set of layers, wherein the index of refraction of each corresponding layer of the first set of layers is different than the index of refraction of each corresponding layer of the second set of layers.
