Abstract

An apparatus includes a substrate, at least one type of tuning material, and a composite material. The substrate has an interface surface or material that manifests, in response to light in a color spectrum, a particular color and a first thermal load. The particular color is associated with the first thermal load. The at least one type of tuning material manifests, in response to light in the color spectrum, the particular color and a second thermal load. The particular color is associated with the second thermal load. The first thermal load is different from the second thermal load. The composite material includes the interface surface or material and the at least one type of tuning material. The composite material manifests, in response to light in the color spectrum, the particular color and a tuned thermal load which is different than the first thermal load and the second thermal load.

First claim

What is claimed is:

1. An apparatus comprising:
a substrate having an interface surface or material to manifest in response to light in a color spectrum, a particular color and a first thermal load, the particular color being associated with the first thermal load for the interface surface or material;
at least one type of tuning material to manifest in response to light in the color spectrum, the particular color and a second thermal load, the particular color being associated with the second thermal load for said at least one type of tuning material, wherein the first thermal load is different from the second thermal load; and
a composite material, including the interface surface or material of the substrate and the at least one type of tuning material, to manifest in response to light in the color spectrum, the particular color and a tuned thermal load which is different than both the first thermal load and the second thermal load.

2. The apparatus of claim 1 , wherein the composite material, when exposed to light in the color spectrum, retains the particular color while changing temperature in response to the light according to or to reflect the tuned thermal load.

3. The apparatus of claim 1 , wherein the composite material is part of apparel that, when exposed to light in the color spectrum, manifests the particular color and the tuned thermal load.

4. The apparatus of claim 1 , wherein the composite material is part of an automobile that, when exposed to light in the color spectrum, manifests the particular color and the tuned thermal load.

5. The apparatus of claim 1 , wherein the composite material is part of a building that, when exposed to light in the color spectrum, manifests the particular color and the tuned thermal load.

6. The apparatus of claim 1 , wherein the composite material is included in means for indicating movement direction.

7. The apparatus of claim 1 , wherein the composite material includes at least two from the group consisting of: chemicals to manifest the particular color, metal oxide particles to manifest the particular color, and dyes of selected concentration to manifest the particular color.

8. A method comprising:
providing at least two materials, the at least two materials being characterized as manifesting, in response to light in a color spectrum, a particular color that is common to each of said at least two materials, and the said at least two materials being characterized by first and second thermal loads; and
providing a composite that includes the at least two materials, the composite being characterized as manifesting a tuned thermal load, in response to light in a color spectrum, wherein each of the tuned thermal load, the first thermal load and the second thermal load are different from each of the other two thermal loads.

9. The method of claim 8 , further including providing a substrate and coating the substrate with the composite as a cover layer above the substrate.

10. The method of claim 8 , wherein providing the at least two materials includes providing a plurality of the at least two materials which refer to or include different chemicals, and further including combining different chemical components as pigments for the composite.

11. The method of claim 8 , wherein at least one of said at least two materials refers to or includes metal oxide particles, the metal oxide particles to manifest the particular color.

12. The method of claim 8 , wherein the at least two materials refers to or includes dyes of selected concentration to manifest the particular color.

13. The method of claim 8 , wherein at least one of said at least two materials refers to or includes dielectric particles to manifest the particular color.

14. The method of claim 8 , wherein at least one of said at least two materials refers to or includes dielectric and conductive particles to manifest the particular color.

15. The method of claim 8 , wherein at least one of said at least two materials refers to or includes a synthetic material, composed of polymer or plastic, to manifest the particular color.

16. The method of claim 8 , wherein a plurality of the at least two materials refer to or include two or more from the following: different chemicals to manifest the particular color, metal oxide particles to manifest the particular color, and dyes of selected concentration to manifest the particular color.

17. The method of claim 8 , wherein a plurality of the at least two materials refer to or include two or more from the following: different chemicals to manifest the particular color, metal oxide particles to manifest the particular color, dielectric particles to manifest the particular color, synthetic material, and dyes of selected concentration to manifest the particular color.

18. The method of claim 8 , wherein at least one of the two materials refers to or includes organic molecules, the organic molecules to manifest the particular color.

19. The method of claim 8 , wherein the at least two materials are used in a set of at least two layers that are secured to one another to manifest the particular color.

20. The method of claim 8 , wherein the at least two materials are integrated together to form the composite.
