This article describes the methods used for coloring anodized aluminum coatings: integral coloring, electrolytic coloring, chemical coloring, and organic dyeing. It discusses organic dye chemistry in terms of single-component organic dyes and multicomponent dyes. The article reviews optimal dyeing conditions, such as temperature, time, concentration, and pH. It concludes with a discussion on the factors considered for choosing a coloring method: the desired shade, light fastness, heat fastness, and contamination.
