Holograms is kind of technique to reconstruct predesigned images. The traditional hologram could't store optical information with polarization which means it is polarization unswitchable, and the photoresists are always rather thick compared to the wavelength of light. In the past decade, metatarsals show the tailored and anomalous optical properties. Furthermore, metasurfaces as a subcategory of metamaterials have demonstrated with distinguished phase modulation and polarization conversion to incident light. However, the color multiplexing device has't demonstrated yet. The aluminum as a potential candidate for pushing plasmonics resonance into UV region in order to generate blue light by metasurface. So here we present a phase modulated multi-color meta-hologram (MCMH) based on aluminum plasmonics, that enables formation of polarization-dependent images with three primary colors.
