Abstract
A composition includes a first coating electrolytically or electrolessly deposited on a surface of a fixture, a middle layer on the first coating, and a colored oxide in contact with at least a portion of the middle layer, wherein the middle layer includes two or more of zirconium, chromium, titanium, hafnium, and aluminum. A method for selective coloration of a surface includes depositing a coating supported by the surface, applying a first laser to ablate a portion of the coating, and applying a second laser to create a colored oxide at the ablated portion.
