And while in theory nothing would stop a blue western god from hanging out with the yellow northeners, gods squabble. So long as it's just intra-pantheon squabbling, any resulting snarl-like manifestations are single color and easily dealt with. Inter-pantheon dealings are formal and removed because the risks are so high. If someone with a different color starts hanging out like they were family, they'll most likely start squabbling like family but the risks will be much worse.
Er, I should clarify. I meant there's nothing stopping a mortal from converting (eg, a human born in Azure City could, if they were so inclined, become a worshiper of Odin or Ereshkigal).
