Abstract
An article having a metal surface is treated to have one or more desired optical effects. The surface is anodized to create an anodic film having pores therein. In some embodiments, an electrodeposition process is performed to deposit one or more metals within the pores of the anodic film. In some embodiments, a pre-dip procedure is performed prior to electrodeposition to create a more uniformly colored anodic film. In some embodiments, one or more dyes are deposited within the pores of the anodic film. In some embodiments, the substrate is exposed to a chemical etching process prior to anodizing to create a micro-textured surface that enhances the richness of the color of the anodic film.
