Add Weapon Dyes!
I could see it if the weapons had their own set of ‘metallic’ dyes. Just 2-3 extra options would make a world of difference. Colors like; Iron, Copper, Gold, Silver, Black Steel, Cobalt, etc. Even though not all weapons would have metal – it would be a cool option for the ones that do.
If they didn’t design the weapons with the ability to change colors then it would be a lot of work to add it… chances are we probably wouldn’t see anything like this in the near future.
It’s a good suggestion though, I support.
