"Auras are the physical manefestation of the electric field surrounding each and every living thing.
That is what causes shocks if you touch something metal. Some persons have the ability to see these
auras, which have different colours, depending on the person. 
   White -- a lot of energy being sensed. 
   Red -- Physical Energy; physically-based person personality or sensuality. Harsh reds tend to
indicate emotionally charged physical animation, usually anger. warm reds, sensuous, or physically
charged and healthy. 
   Orange -- Friendly, open, approachable 
   Yellow -- Intellectual, thinking, working faculties. 
   Green -- Healthy, balanced, calming, charming, agenda sensualness, sensible or coniving. 
   Blue -- Intellect but calm reserved, spiritual, convinced; sometime an integrated personality
exuding charisma. 
   Violet -- Spiritual, sensitive, focused but not necessarily in reality. 
   Purple -- It is a combination of Blue and Red, a mixed bag and a spectrum of what it could be. 
   Pink -- physical energy being diffused, hence it is a calming color. 
   Lime Green -- Not many have this color and are balanced; usually stress-related. 
   Browns -- One just have to work on if and get a feel. Could be warm rich and well integrated
person, or a one who is unhealthy, or just to much going on (different types of stress). 
   Black -- Nothing getting out, shielding or hiding. Total absorbtion. Do you feel tired? Do you feel
the world sucking around you? Or is it like a flat black but you sense a scintallation of your own
energy being diffused out? In other words, is there a metallic tint? If you feel drained, it could be a
"psychic vampire". Otherwise, it may be someone who is very skilled who doesn't want to be
noticed, scanned or bothered. Usually the colors when viewed with these people tend to be more
metallic. Many people misinterpret these also. 
   Mixed shades (Like mixed reds) -- mixed emotion, stability should be questioned which flavor is
going to push what in what direction, generally not based in reality."
