So, I know the naming rule of RWBY, but I was wondering, is the rule flexible with how it is used? For example, if one were to create a character or Rooster Teeth were to suddenly make a sequel to the series, could there be a character named Ragnar, due to the historical Viking King Ragnar having the bluest of eyes? Basically, does it have to correspond with a color (Ruby being, well, Ruby) or can it be a name associated with someone who has a very distinct color that they often praised/famous for or has as a title (Ragnar for Blue/Red, as there is Historical Ragnar and Ragnar the Red from TES)?
