But isn't red usually associated with Gluttony, and green, with Wrath? And maybe the Demon of Greed found Prim's soul incompatible and has some strange preference for the soul of Adam Moonlit? That would explain why it latched on to either Kyle's soul or Gallerian's soul (assuming Gallerian is a reincarnation of Adam).
