The article includes at least one color change portion capable of changing colors. The color change portion includes composite material including a photonic lattice. The color change portion can change colors according to one or more performance parameters. The article can be connected to a computer and the color change portion can be controlled using the computer ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 An article comprising: a first panel including a first surface defining an exterior surface of the article, the first panel including an aperture; and a color change portion attached to the first panel and extending at least partially across the aperture, the color change portion including (i) an outer surface recessed from the exterior surface of the first panel and (ii) a photonic lattice operable to receive an electrical signal to change a color of the color change portion. ### Claim 22 (depends on 21) The article of claim 21, wherein the article is one of an article of clothing, an article of footwear, or an article of equipment. ### Claim 23 (depends on 21) The article of claim 21, wherein the outer surface extends across an entirety of the aperture. ### Claim 24 (depends on 21) The article of claim 21, wherein the photonic lattice is a component of a composite material. ### Claim 25 (depends on 24) The article of claim 24, wherein the composite material includes a first conductive layer electrically connected to a first terminal and a second conductive layer electrically connected to a second terminal. ### Claim 26 (depends on 25) The article of claim 25, wherein the first conductive layer and the second conductive layer are disposed on opposite sides of the photonic lattice. ### Claim 27 (depends on 25) The article of claim 25, wherein the photonic lattice is printed on one of the first conductive layer and the second conductive layer. ### Claim 28 (depends on 25) The article of claim 25, wherein the first terminal and the second terminal are in electrical communication with at least one of a control unit and a power source operable to change a color of the color change portion by changing dimensions of the photonic lattice. ### Claim 29 (depends on 25) The article of claim 25, further comprising a protective layer disposed over one of the first conductive layer and the second conductive layer, the protective layer defining the outer surface of the color change portion. ### Claim 30 (depends on 29) The article of claim 29, further comprising a substrate disposed over the other of the first conductive layer and the second conductive layer. ### Claim 31 (depends on 21) The article of claim 21, wherein the first panel includes a second surface formed on an opposite side of the first panel than the first surface, the second surface being in contact with the outer surface of the color change portion adjacent to the aperture. ### Claim 32 (depends on 31) The article of claim 31, further comprising a second panel attached to the color change portion on an opposite side of the color change portion than the outer surface, the second panel defining an interior surface of the article. ### Claim 33 An article comprising: a first panel including a first surface defining an exterior surface of the article, the first panel including an aperture; and a color change portion attached to the first panel and extending at least partially across the aperture, the color change portion including (i) an outer surface substantially flush with the exterior surface of the first panel and (ii) a photonic lattice operable to receive an electrical signal to change a color of the color change portion. ### Claim 34 (depends on 33) The article of clothing claim 33, wherein the outer surface extends across an entirety of the aperture. ### Claim 35 (depends on 33) The article of clothing of claim 33, wherein the photonic lattice is a component of a composite material. ### Claim 36 (depends on 35) The article of clothing of claim 35, wherein the composite material includes a first conductive layer electrically connected to a first terminal and a second conductive layer electrically connected to a second terminal. ### Claim 37 (depends on 36) The article of clothing of claim 36, wherein the first conductive layer and the second conductive layer are disposed on opposite sides of the photonic lattice. ### Claim 38 (depends on 36) The article of clothing of claim 36, wherein the photonic lattice is printed on one of the first conductive layer and the second conductive layer. ### Claim 39 (depends on 36) The article of clothing of claim 36, wherein the first terminal and the second terminal are in electrical communication with at least one of a control unit and a power source operable to change a color of the color change portion by changing dimensions of the photonic lattice. ### Claim 40 (depends on 36) The article of clothing of claim 36, further comprising a protective layer disposed over one of the first conductive layer and the second conductive layer, the protective layer defining the outer surface of the color change portion. ### Claim 41 (depends on 40) The article of clothing of claim 40, further comprising a substrate disposed over the other of the first conductive layer and the second conductive layer. ### Claim 42 (depends on 33) The article of claim 33, wherein the first panel is in contact with the color change portion adjacent to the outer surface of the color change portion. ### Claim 43 (depends on 42) The article of claim 42, further comprising a second panel attached to the color change portion on an opposite side of the color change portion than the outer surface, the second panel defining an interior surface of the article.
