Morpho butterfly's blue is the structural color given by optical interference, that contradicts its single coloration in too wide angular range. After proven the principle of the coloration by mimicking the specific nanostructures of their scales, we found the reproduced Morpho-color to serve wide applications, because it can produce a brilliant single color in wide angular range with high reflectivity for longtime without chemical pigment. We have then developed various techniques for practical applications of the specific color. One of the remaining issues is to mass-produce the large-area flexible film, which has long been difficult because of the process containing both nano-imprint and multilayer deposition. Thus, we developed a new process using the flexible mold and simple film-detachment system.
