A couple of times though everything has flashed luminous green. If any of you can remember old cameras that used to have films (i.e. negatives), my vision looked as though I was viewing my opponent through a luminous green negative.
Yeah, I once hit someone with a good overhand once, he described this same sensation to me. I saw I stunned him pretty bad, after the round asked him about it he said "whole ring turned green".
