Claim 0:
1. An article comprising:
an optical element on a surface of the article, wherein the optical element has a first minimum percent reflectance in a first wavelength range within a wavelength range of about 380 to 625 nanometers, wherein the first wavelength range has a first width of about 10 to 245 nanometers, wherein the first minimum percent reflectance is about 50 percent or more, wherein the optical element imparts a structural color that corresponds substantially to the first wavelength range, wherein the structural color has limited iridescence such that, when each color visible at each possible angle of observation is assigned to a single hue selected from the group consisting of a primary, a secondary and a tertiary color on a yellow and blue (RYB) color wheel, all of the assigned hues fall into a single hue group, wherein the single hue group is one of a) green-yellow, yellow, and yellow-orange; b) yellow, yellow-orange and orange; c) yellow-orange and orange; d) purple; e) purple and purple-blue; f) purple, purple-blue, and blue; g) purple-blue, blue, and blue-green; h) blue, blue-green and green; and i) blue-green, green, and green-yellow.
