Hi Larisa!
I'm not sure about most people, but for me the aura usually surrounds the object I am looking at, so it incorporates what I am viewing as well as the area at least a few feet out from that. The colors in the auras seem to vary a lot.
An after image is closer to the actual size of what I viewed and doesn't have the energy radiating out from the core item.It is also usually the complementary color of what I was looking at.
It will be interesting to see what others perceive!
