And it's worth considering that this issue isn't unique to image generation, either.
Santa didn't always wear red.
Granted, but not the best example, red and green are the emblematic colours elves wore in northern european cultures. Santa is somewhat syncretic with Robert Goodfellow or Robin Redbreast, Puck, Puca, etc etc. it wasn’t really a cola invention.
E.g., I think, there are now entire generations, who never played anything as a child that wasn't tied in with corporate IP in one way or the other.
