A plasmonic nano-color coating layer includes a composite layer including a plurality of metal particle layers and a plurality of matrix layers and having a periodic multilayer structure in which the metal particle layers and the matrix layers are alternately arranged, a dielectric buffer layer located below the composite layer, and a mirror layer located below the dielectric buffer layer, wherein the color of the plasmonic nano-color coating layer is determined based on a nominal thickness of the metal particle layer and a separation between the metal particle layers.
