Also backs of heads reference #131
As the purveyor of #131, I will point out that the back of the blue haired woman was a main point of picture (as compared to the lavender/pink of the tree she is walking under and the colors of the girls outfits and the tattoo of the other woman- part of the reason the pic is in full living color). Color is often not used in street photography, but this is one of those images (IMO) that screams for color.
