Abstract
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 through the use of an optical element, where structural colors are visible colors produced, at least in part, through optical effects. The optical element (e.g., a single layer reflector, a single layer filter, a multilayer reflector or a multilayer filter) can include the reflective layer(s), constituent layers, and an optional textured surface. The optical element has a minimum percent reflectance in a wavelength range within the wavelength range of about 380 to 625 nanometers. The optical element imparts a structural color that corresponds substantially to the range of wavelength range.
