Abstract

A colored mirror includes a transparent substrate, a reflective metal layer and at least one interface layer between the substrate and the metal layer, wherein the interface layer includes at least one discontinuous metal layer, and at least one overlayer of a dielectric material deposited on the discontinuous layer. The discontinuous metal layer allows the adaptation of the color reflected by the mirror. The nominal thickness thereof and the type of material, as well as the nature and thickness of the dielectric overlayer, play a role in obtaining the color of the mirror.
