7.1.1 Introduction

Colors produced by light phenomena, such as interference, diffraction, and scattering of light, are generally called structural colors [1-8]. In recent years, structural colors have attracted considerable attention, particularly in the field of photonics, where sophisticated next-generation photonic materials are of interest, and in industries where novel, visually appealing materials are in demand, for example, for use in fibers, paints, cosmetics, and jewels. In nature, structural colors are widely distributed in living things, accompanying surprisingly elaborate nanostructures, and have been a subject of extensive studies for more than a century [9-15].
