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. Spikorís mace, Fakerís sword and armor, Stinkorís armor, Man at Arms armor, Tri-Klops wrist armor, Whiplash spear, Jitsuís sword, Webstorís gun, Man e Faceís gun, and Iím sure there are more.
So I got to thinkingÖ 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 Marvelís adamantium. Thoughts?
