The color Orange in MOTU(C)

When looking over my collection of MOTUC the other day, it dawned on me that there is a lot of orange. Spikor’s mace, Faker’s sword and armor, Stinkor’s armor, Man at Arms armor, Tri-Klops wrist armor, Whiplash spear, Jitsu’s sword, Webstor’s gun, Man e Face’s gun, and I’m sure there are more.
So I got to thinking… there must be a very strong metal or oar on Eternia that has an orange color that is good for making armor and weapons. Maybe sort of like Marvel’s adamantium. Thoughts?
