The image shows a schematic representation of close-packed multilayer reflecting columns with the same periodicity but with random variations in location, both in horizontal and vertical dimensions, that form the Morpho-mimetic thin-film structural color reflectors described in the manuscript by J. H. Shin and co-workers, on page 2375. Overlaid are photographs of an actual Morpho butterfly, a 6-inch diameter Morpho-mimetic thin film that demonstrates its color, brightness, and flexibility, and images of cyan, green, and red ‘Morpho butterflies’ created from photos of Morpho-mimetic thin films with corresponding colors.
