Abstract Structural color is a remarkable physical phenomenon that exists widely in nature. Unlike traditional rendering methods, they are realized mainly through micro/nanostructures interfere, diffract, scatter light, and exhibit long‐life environmental‐friendly effects. In nature, few organisms use their color‐changing system to transmit information, such as courtship, warning, or disguise. Meanwhile, some natural inorganic minerals can also structural colors. Learning from scientists have achieved large‐scale design manufacturing technology for artificial photonic crystals. Photonic crystals unique microstructure forms band gap under the action of periodic potential field, consequently causing Bragg scattering due arrangement different refractive index media within them. Because apparent ability form local photons at crystal defects, been extensively studied recent years broad application prospects fibers, optical computers, chips, other fields. this review, research, properties, applications presented, well insight into future developments
