Abstract: In an example, a device cover may comprise a substrate and a metal luster layer having a lustrous paint formulation applied to an outer surface of the substrate. The lustrous paint formulation may comprise base particles with surfaces partially coated with metal nanoparticles. The metal nanoparticles may be disposed in a non-continuous manner on the base particles.
