but i guess if you can't corelate the aura phenomena directly and intensivly with ppl mind it is not the aura phenomena with color description and things, and there some other ppl here that have synetesia too and it look like this too
like cruboo and some other ppl spoke about this
and it is something quite intense and you instinctivly relate with 'soul color' or ppl emotions, or impact that a thing or a situation a music or any art or whatever will have on ppl or on you etc
but in the same time it is not something that 'overlap' into the vision it is really mental , but well i don't know after all maybe some ppl really see this color visually around object after all lol
