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.
