An article with a color change portion and a method of changing color. 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.

Presented are manufacturing systems, methods, and devices for forming footwear using scrap or waste plastic materials. A method for manufacturing an article of footwear, such as an athletic shoe, begins with receiving a batch of recycled plastic, which may include thermoplastic elastomers or ethylene-vinyl acetate, and grinding the batch of recycled plastic material. The ground recycled material is processed, for example, by adding a foaming agent that activates at elevated temperatures. The processed recycled material is placed into the internal cavity of a final mold that is shaped like a segment of the footwear, such as a unitary sole structure. To form the footwear segment, the processed recycled material is heated past the threshold activation temperature of the foaming agent such that the foaming agent causes the recycled material to expand and fill the internal cavity of the final mold. The formed footwear segment is then extracted from the mold.

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 optical element can have different sections that have different relative thicknesses. For example, a first section of the optical element disposed on the first area of the article can have a first average thickness and a second section of the optical element disposed on the second area can have a second average thickness. The first section of the optical element imparts a first structural color and the second section imparts a second structural color.

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 surface of the article can include the optical element with sections that have different relative thicknesses from one another. A first section imparts a first structural color and a second section imparts a second structural color. The first structural color and the second structural color differ from each other when viewed from the same angle of observation from a viewer having 20/20 visual acuity and normal color vision from a distance of about 1 meter from the article including the optical element.

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 includes the optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., cross-sectional structure) of the optical element in certain regions.

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 includes the optical element on its surface and the optical element includes one or more layers (e.g., a reflective layer(s), a constituent layer(s), and the like). The optical element can include a plurality of different sections, where each of the different sections have a different relative thickness.

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 includes the optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., transverse cross-sectional structure) of the optical element in certain regions.

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 an optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., transverse cross-sectional structure) of the optical element in certain regions.

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.

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 present disclosure provides for articles (e.g., structurally colored articles) that exhibit different structural colors in different regions of the article using an optical element, where the optical element has different structures (e.g., cross-sectional structures) in at least two of those regions.
