Coloring is subtle in this photo. This is a few minutes after I stopped walking and pulled my shoes and socks off. Foot looked bright red, in full flare, at first. Then, the bright red changes to a bluish purple.
I have a picture that looks eerily similar to this! And it was kind of the same thing. I was in full flare, took everything off, put my feet on the floor, and when I looked again, this is exactly what I saw! So weird!
