It's also based on an Indian elephant, the Indian part very in your face with not only the smaller ears but Rajah right in the name, which is an Indian king/prince.
And finally, it's also based on verdigris, the name for the green discoloration that covers copper. That's why Cufant is orangish (the color of copper) and Copperajah is green covering that orangish base. The Statue of Liberty is an example of something that was copper and then taken over by the green coloring of verdigris over time.
