Anodization is the process used to give the final finish to aluminum to improve corrosion resistance. This technique is often used for the components of precision devices, such as computers and cameras. This dyeing process is not a pigment paint but a sealing process in which dye is poured into pores on the porous surface from the anodizing process.

This dyeing and finishing add a touch of deepness to the aluminum and make possible the creation of a range of colours and tones depending on the anodizing process, the density of the dye, and the duration of dye application.
