Chemical coloring of metals is the process of changing the color of metal surfaces with different chemical solutions. The chemical coloring of metals can be split into three types: electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or ...
Electrochemical coloring of metals is a process in which the surface color of metal is changed by electrochemical techniques, i.e. cathodic or anodic polarization. The first method of electrochemical coloring of metals are certainly Nobili's colored rings, discovered by Leopoldo Nobili , an Italian physicist in 1826.

This process was repeated until the desired depth of color was achieved or the metal simply did not color further. This is one of the reasons rust and fume bluing are generally more rust-resistant than other methods. The parts are then oiled and allowed to stand overnight. This process leaves a deep blue-black finish. [8]

The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag.
A metallic color is a color that appears to be that of a polished metal. The visual sensation usually associated with metals is its metallic shine . This cannot be reproduced by a simple solid color , because the shiny effect is due to the material's brightness varying with the surface angle to the light source.
Among the rules: the sun must have 12 rays, both the sun and moon must be white, and the border color is specified as “deep blue.” ...
