Yes, but when I started seeing them I went to the library, and what I see is definately NOT what most books teach.
Black for me is not about evil but about intensity of focus.
Red or Orange is generally some kind of pain or irritation.
Golden is generally a kind of vibrant health or pregnancy.
Purple is something I have been calling a 'chakra-shot', but happens most often for 'regular' people when they sneeze.
Generally, if I see some colors that I don't immediately know what they mean, I can meditate on the situation and/or have a pendulum conversation with my subconscious, and figure out what they mean.
I have never seen any big golden eggs around any people.
I have seen Kirlian Photo-s, those are not the colors or arrangements I see.
I have seen translucent darts, daggers, arrows, axes, etc. These seem to get formed when someone glares at someone else that they really resent, and then these 'aura weapons' hover around that person until either they cleanse, or they have some kind of 'accidental injury' to that part of themselves where the 'aura weapon' was hovering.
I hope this helps you.
