i cant remember who it was but in a thread someone suggested that coloured orbs are like auras and reflect the 'mood' of the orb. i think that this explanation works best for me because auras are specific to individuals and i believe that they can be specific to orbs too. I dont want this idea to seem like my own someone else did mention it first! But it is a very good explanation
