Not much aside from flavor really. I imagine a red aura coming from a fire user or someone with a hot temper, blue for a calm collected individual, etc.  

Though high concentrations of energy/mana/chi usually either reveals a magic user or someone who manipulates energy. (or has untapped potential to do so) 

Skallagrim and the rest of the Dreamers would look like walking well-pools of amethyst.

Well, assuming the colour is based on the personality and the intensity is based on power, Metz would probably have a very washed out and faint aura. Can't decide on a colour though, it might be a grayish/white-ish nodescript sort of colour.
