lololol. You don't ACTUALLY believe in auras, do you know? Besides the fact that it probably is 'pagan':
If you stare at something long enough, your nerve receptors for the color(s) you see most get 'used' to the color. If you chance your vision the smallest bit, you will see the negative of the color the person is wearing.
Look at some one in a black dress: White aura. Green dress, red or whatever aura.
TOTAL. BULLCRAP. Thank you.
EDIT:
Nice ancient way of looking at philosophy. They used to think that by introsection you could 'find the higher truth'. As far as I know everyone accepted that sources from the outside are needed to phisophise. Even if you conclue a certain chair appears red to you, that is science in way.
Science > faith. Philosophy > not thinking. They are 2 different subjects, one isn't better then another.
