RE:lolThe best time I've had Wango while learning. The color (according to my IPad) is a light gray...perhaps white. So those aren't copper is my guess....and silver if I'm correct isn't on the list...nor is platinum. So I'm down sizing to Nickle (but I'm not sure that's on our list at this point). Bro I'm thinking Lead, Zinc or Cobalt as I've never seen a blue lichen.
