Multi-scale hierarchical structures with period spanning from 4 μm to 300 nm and height spanning from 0.9 μm to 40 nm were fabricated by angle-multiplexed exposure of two-beam interference. Colors from violet to red can be seen by gradually lowering the viewing angle. The proposed method of surface printing can be easily adopted for randomized patterns, which can find potential applications in antifouling, colored jewelry, and SERS sensors.
