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.

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 (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 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.

A hidden patterned structure, applicable to an electronic vaporization device, includes: a base surface; and a plurality of patterned cells protruding from the base surface. Each patterned cell of the plurality of patterned cells includes at least two chamfered surfaces, the at least two chamfered surfaces being at different angles relative to the base surface. At least one patterned surface is formed on at least one chamfered surface of the at least two chamfered surfaces of at least a portion of the plurality of patterned cells. The at least one patterned surface has a different surface roughness and/or is at a different height from a chamfered surface corresponding to the at least one patterned surface.

A three-dimensionally printed object includes a plurality of different material regions that together define a surface region of the object. The plurality of different material regions includes a first material region and a second material region. The first material region has a first color, and the second material region has a second color that is different from the first color. The different material regions overlap from each other within the object by different amounts viewed from different directions so that different proportions of light from the plurality of different material regions are visible to an observer viewing the surface region of the three-dimensionally printed object from different view directions, different view angles, and with illumination lighting the surface region at different angles. A coloration of the surface region is altered based on the proportions of light from the plurality of different material regions visible to the observer.

The present disclosure relates to a decoration member comprising a color developing layer comprising a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer, wherein the light absorbing layer comprises a molybdenum-titanium oxide (Mo.sub.aTi.sub.bO.sub.x).

A color shifting heat transfer label includes a carrier and a color design layer on the carrier. The color design layer is formulated from an ink having a color shifting effect. The color design layer is configured to separate from the carrier to define a color shifting feature that is adhered to a target object upon application of heat and pressure. The color shifting feature is adhered to the target object to define a plane defined by the color shifting feature such that the color shifting feature exhibits a first color when viewed from an angle of about 90 degrees relative to the plane defined by the color shifting feature and a second color, different from the first color when viewed from an angle of about 45 degrees or less relative to the plane defined by the color shifting feature.
