Abstract: Porous metal oxide layers having a color due to visible light interference effects are disclosed. In particular embodiments the porous metal oxide layers are formed using an anodizing processes, which includes a porous metal oxide layer forming process and a barrier layer thickening process. The barrier layer thickening process increases a thickness of a barrier layer within the porous metal oxide layer to a thickness sufficient to and cause incident visible light waves to be reflected in the form of a new visible light waves, thereby imparting a color to the porous metal oxide layer. Methods for tuning the color of the porous metal oxide layer and for color matching surfaces of different types of metal substrates are described.
