Correct me if I'm wrong here, but unlike aluminum, which is essentially dyed during the anodization process, with titanium the colour is achieved through altering the surface molecules with an electrical current. The amount of voltage determining the colour. The way light reflects off the altered surface creates the colour your eye sees. If I'm right, the blue on the titanium stud is a surface texture of sorts that will polish off with your finger, it's not really the same as a hardened coating, or the ano process with aluminum where dye soaks into the open pores of the metal. Does anyone know how CRK gets that blue? Certainly not the Chinese based on the goofy looking fake 25's with rainbow studs.
