As you may/may not know, i'm doing the "Raising the Bar" shocker project, and i've been drawing up some designs for engraving, and i changed my color scheme to let the engraving show, but i've seen guns with different color engravings, only black, but like this one from OddPB:
is that a tattoo or whatever? or is it engraving? can i do that to my shocker?
also, how is that done?
PS: Sorry if i'm a noob at this, or if it's a stupid question, just wondering.
