As an important characteristic of many creatures, structural colors play a crucial role in the survival of organisms. Inspired by these features, an intelligent structural color material with a heterogeneous striped pattern and stimuli‐responsivity by fast self‐assembly of colloidal nanoparticles in capillaries with a certain diameter range are presented here. The width, spacing, color, and even combination of the structural color stripe patterns can be precisely tailored by adjusting the self‐assembly parameters. Attractively, with the integration of a near‐infrared (NIR) light responsive graphene hydrogel into the structural color stripe pattern, the materials are endowed with light‐controlled reversible bending behavior with self‐reporting color indication. It is demonstrated that the striped structural color materials can be used as NIR‐light‐triggered dynamic barcode labels for the anti‐counterfeiting of different products. These features of the bioinspired structural color stripe pattern materials indicate their potential values for mimicking structural color organisms, which will find important applications in constructing intelligent sensors, anti‐counterfeiting devices, and so on.
