Abstract
As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article can include the optical element (e.g., a single layer reflector, a single layer filter, a multilayer reflector or a multilayer filter) including one or more layers (e.g., a reflective layer(s), a constituent layer(s), and the like). The surface of the article can include areas of the surface that are at different relative heights from one another and can impart different structural colors.

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 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.
A structure comprising:
- an optical element disposed on a surface of an article, wherein the surface of the article includes a base surface and at least a first surface and a second surface, wherein the first surface has a first vertical height relative to the base surface and the second surface has a second vertical height relative to the base surface,
- wherein the optical element includes a first section disposed on the first 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 first 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.
A structure comprising:
- an optical element disposed on a surface of an article, wherein the surface has a base surface and has one or more protrusions having a protrusion surface, or one or more indentations having an indentation surface, or both one or more protrusions and one or more indentations;
- wherein the optical element includes at least a first section disposed on the base surface, a second section disposed on the protrusion surfaces, or a third section disposed on the indentation surfaces, or disposed on two of each of the base surfaces, the protrusion surfaces, or the indentation surfaces;
- wherein the first section of the optical element imparts a first structural color to the base surface, the second section of the optical element imparts a second structural color to the protrusion surface, and the third section imparts a third structural color to the indentation surface, and wherein at least a pair of the first structural color, the second structural color, and the third structural color are different 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 includes a first height difference between at least one pair of the base surface, the protrusion surface, or the indention surface;
- wherein the optical element comprises at least one constituent layer, wherein the number of constituent layer(s) of two or three of the first section, the second section, and the third section are the same.
