An article of footwear may include an upper with an outer layer, an inner layer, and a chamber element positioned at least partially between the outer layer and the upper layer. The chamber element may be formed of two layers of a transparent colored polymer material and may be sealed to enclose a fluid. The chamber element may also have a plurality of subchambers. The outer layer may have a plurality of apertures. Each subchamber may protrude at least partially through a corresponding one of the apertures.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color.

A subtractive color change system for displaying a selected color to a viewer and a method of changing color. The system includes a layered assembly having transparent panels of primary and key colors, with a fixed-color background behind the layered assembly. The subtractive color change system may have a control unit to individually control the intensities and values of the primary color panels to render a color and to control the intensities and values of the panels in the layered assembly to reduce differences between the color rendered and the selected color and to display the selected color to a viewer.

Components of articles that include an optical element that imparts structural color to the component are provided. Methods of making the components including the optical element, and methods of using the components such as to make an article of manufacture are provided.

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).

One or more aspects of the present disclosure provide components for an article of manufacture, having a film with an optical element that imparts a structural color to the component. The present disclosure also provide methods for making components with the films and optical element, and articles of manufacture including the component.

One or more aspects of the present disclosure are directed to components having an optical element that imparts structural color to the component or article. The present disclosure is also directed to articles of manufacture including the component having an optical element, and methods for making components and articles having an optical element that imparts structural color.

In example aspects, materials are repurposed for article manufacturing. That is, in some instances, materials in the manufacturing supply chain are potentially subject to disposal. However, aspects of this disclosure sustainably repurpose those materials (that might otherwise be disposed of) to be used in articles. In some aspects, the repurposed materials may be obscured with a concealing layer.

One or more aspects of the present disclosure provide optical element transfer structures that include an optical element releasably coupled with a transfer medium and methods of making and using the optical element transfer structures. The optical element transfer structures can be used to dispose an optical element onto an article, whereby the optical element imparts a structural color to the article.
