Color filters utilize optical resonance in thin-film nanostructures to obtain vivid reflective or transmissive colors, which has attracted a lot of attention recently. Here, we report the angle-insensitive color filters targeting different wavelengths and applications, which can be achieved by metal-dielectric-metal structures. Certain combinations of metals and dielectrics are selected to achieve efficient angle-insensitive color filters. The type and the depth of the material both have a significant influence on transmission efficiency. We expect that our work will provide some new insights for structure color applications.
