Aura is real and not a hippie stuff, it's just deliberately discredited.
You might want to look up Kirlian photography. Instead of Wikipedia look for books.
The color of an aura is determined by frequency. It's all about energy. It's not an esoterical concept, it's just pure physics.
The aura color range depends on the personality and energy level. People who are doing down to earth stuff are red, the people who are more spiritual are blue and people who are "extremely" spiritual or enlightened are white, but so are very old people, or people who are close to death. Please note: this is just a quick rundown on colors.
The old Kirlian photography was literally making a photograph. The Kirlian brothers photographed a man without a leg and the missing leg's outline showed up in the photograph.

Stuff like "Aura video station" and "Auracloud 3d" (look it up) works and legit but they are not actually photographing the aura, they are determining it's color by the frequency that's being measured with a biosensor. It produces almost the same result as the old photography way.
These new aura devices and softwares can make reports about your mind/body state, evaluate your health, detect health risks, diseases, measure the strenght of your chakras (they are like funnels of energy). This new aura measuring technology is very professional and accurate. Quite expensive too. But all you need is a laptop then you can hook up the camera and the biosensor through usb.
I was working as an assistant for a person who was doing this aura photography for a living. We was doing it for about 20-50 people/day. there were tons of "skeptics" but they all left with dropped jaws because of the accuracy of the reports.
This is a device you can not lie to, and the entire aura topic is discredited as new-age hippie stuff because the modern aura measuring technology can give you a low level anaylsis of your mind/body/health/personality and accessible to everyone (if you have the money, about 20k usd).
So to quickly summarize it there are two types of aura photography:
- the old Kirlian method which is an actual photograph taken at the moment when this electronic discharge happen
- new method without an "actual" photograph of your aura, your energy levels and frequencies are being read by a biosensor then the software will show your aura color based on your data.
The aura is very real since it can be photographed and measured. Basically your aura contains raw data and your aura is not a pesudo-esoteric hippie fuckery, it's your actual electronic energy field. Everyone and everything has an aura.
Some people can see it without any kind of device.
