Bioinspired structural colors are attracting increasing attention in photonics, display, labeling and so forth. High-resolution and stable coloration is significant but is challenging to be fabricated in a facile and low-cost way. Herein, multilayer architecture containing an internal nanocavity as the structural color unit is obtained conveniently by direct nanosecond laser printing in atmosphere condition. Arbitrary colorful patterns with submicron accuracy can be realized only by a single step. And such structural colors induced by inner structures in the interlayer are antipollutive, antioxidative and easy to clean.
