Abstract
A method for producing an article having a decorative coating includes depositing at least a first coating layer onto at least a portion of a substrate using a physical or chemical vapor deposition method in a vacuum chamber at sub-atmospheric pressure, the first coating layer comprising a first material having a first color. The method also includes patterning the first coating layer using a non-uniform patterning process to form a patterned coating layer having penetrations through which a portion of an underlying surface is visible, the underlying surface comprising a second material and having a second color that is visually contrasting to the first color. The patterned first coating layer comprises a decorative pattern comprising features distinguishable by an unaided human eye.
