I didn't find info on this here, so I figure I'd ask for clarification.
The color of the boss' aura signifies it's class, right? If so, what color are necromancers and what color are rangers? I think I've seen green for both, but can't be completely sure. Not certain about the mesmer too.
Is this correct?:
Yellow - Warrior
Red - Elementalist
Blue - Monk
Light Green - Ranger
Dark Green - Necromancer
Purple/Pink/Something? - Mesmer
Thanks for the help.

That would explain things. Ugh, I got to tweak my contrast or hue or whatever, because I can't tell if its "light" or "dark" when there's a "green" boss standing by it's lonesome. 
and i can sometimes even cant see it 

(That deserves 3 /doh's, a /sorry, and a /bowhead).
