What a great idea...love it!
I'm a skeptic in my own field, meaning, I go through all of the physical possibilities before I jump on it's something para-normal or out of the ordinary. Especially when it comes to houses...oo...ADD moment, Halloween's coming, one of my favorites.
But anyway, the Aura thing? I tend to feel a person's vibe or whatever you call it bubble, being, etc. before I might see color. But when I have seen color around a person, it's never like the artistic paintings I see in the movies or advertising.
Sometimes it's even just a shift in lighting or view, like the negative of something. Like stare at a lamp, then look at a white wall, that type of thing.
Other times, I'll see purple, yellow or a light whitish color, sometimes light blue. But the point is it's faded...not like fires streaming from behind a person.
What's it like for other people?
