Bioinspired organic/inorganic hybrid one-dimensional photonic crystals(1DPCs) are prepared by spin-coating, which is a simple, reproducible, and low-cost approach. The 1DPCs possess fast water-vapor responsiveness and reversible full-color switching. The color of the 1DPCs varies from blue to red under differing humidities, covering the whole visible range. The as-prepared 1DPCs successfully combine structural color and stimuli sensitivity ; they are promising materials for colorful detection in the chemical and biological fields.
