In my line of work I often get sections of free brass or nickle colored bead chain. Is there an easy way to get it to be diffrent colors. I seem to remember reading some where that you can use gun bluing chemical to get them some what black but is there other ways to get them really black? What about other colors like Red or Green. It seems like paint would come off pretty easy but maybe I am wrong. Have any of you out there tried changing the color of bead chain?
