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 that exhibit structural colors using one or more optical elements. The optical element(s) is disposed on a substrate (e.g., the surface of the article) and when exposed to visible light, the optical element imparts a structural color to the article, where the structural color (e.g., single color, multicolor such as iridescent) is visible color produced, at least in part, through optical effects (e.g., through scattering, refraction, reflection, interference, and/or diffraction of visible wavelengths of light). Different optical elements can impart the same or different structural colors.

The present disclosure provides for articles that exhibit structural colors. The article includes optical stacks that can be incorporated onto one or more components of an article, for example, when the article is an article of footwear, on an upper or sole of an article of footwear. Upon being subjected to abrasive forces, one or more of the layers of the optical stacks are removed, which can alter the appearance (e.g., structural color and/or non-structural color of areas) of the article. In this way, an article may have a certain appearance originally, but can change (e.g., randomly or intentionally) upon application of abrasive forces (e.g., through use or intentionally).

The present invention is directed to obtaining an object having an anisotropic reflection characteristic without using a lenticular lens. A print product including a print medium on which a repetitive structure of projected portions and recessed portions is formed out of image forming materials including a color material includes a first layer formed on surfaces of the projected portions out of a first color material among the image forming materials, and a second layer formed on the recessed portions out of a second color material different from the first color material, wherein the projected portions have a height to occlude part of the second layer when observed at an angle different from an angle formed by a normal to a surface of the print medium.

A method is provided for marking a location on a surface of a component. The location defines a normal extending perpendicularly therefrom. The method includes irradiating the location with a first laser beam to create a first mark having a first color. The first laser beam is disposed at a first angle relative to the normal. The method also includes irradiating the location with a second laser beam to create a second mark having a second color different than the first color. The second laser beam is disposed at a second angle relative to the normal. The second angle is different than the first angle.

This specification relates to a decoration member including: a substrate; and a decoration layer provided on the substrate in which there are one or more combinations of viewing angles θ and φ in which a contrast parameter C.sub.n represented by Equation 1 is 0.1 or more.

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.
