Structural coloration generates colors by the interaction between incident light and micro- or nano-scale structures. It has received tremendous interest for decades, due to advantages including robustness against bleaching environmentally friendly properties (compared with conventional pigments dyes). As a versatile strategy, tuning of structural based on nanoscale photonic structures been extensively explored can enable broad range applications displays, anti-counterfeiting, coating. However, scholarly research had limited impact commercial products because their disadvantages in cost, scalability, fabrication. In this review, we analyze key challenges opportunities development colors. We first summarize fundamental mechanisms design strategies while reviewing recent progress realizing dynamic coloration.
