I've come across something interesting in the works of Carl Jung. The significance of this is in the fact that Jung's theories are the foundations for Campbell's theories, and Lucas admits that he is not only a disciple of Campbell but psychology in general - so I'm thinking it's not a big stretch to think this may have influenced him ... In very simple terms, Jung discusses how an individual shifts between instincts and spirituality. But instead of there being just two mutually exclusive states (instincts OR spirituality) there is a continuum with instincts at one pole and spirituality at the other. And then the interesting part: he compares this continuum to the spectrum of colours, with red at one end and blue at the other. He explains that red represents instincts, and blue represents spirituality. Violet, being the combination of red and blue, is the union of spirituality and instincts. Which makes the lightsabre colours in Star Wars that little bit more interesting, IMHO. Red = instincts = Sith Blue = spirituality = Jedi Violet = instinct + spirituality = Mace (there's a reference somewhere, possibly EU *gasp*, about Mace using fighting techniques that border on the darkside...) Anyway, just a little something that might interest some people.
