The Morpho butterfly's blue is an exceptional and special structural color, which has both high brilliance and single color in wide angular range. Considering the high potential of this coloration for wide industrial applications, we have long advanced several applied researches in various directions. We have recently solved a remaining mystery about the optical role of nano-randomness on the butterfly's scale. This analysis based on the numerical simulation can reveal a new relationship between the optical properties of 2D and 3D nanostructures. Since 2D nanostructures are well compatible with nanoimprint lithography, our obtained results may give a clue not only for Morpho-color devices, but more generally for convenient manufacturing methods of optical devices.
