Hey Boogieman, if you think her right fist is this dark because of a "shadow", there is no hope for you. There is NO WAY IN HELL THIS IS A WHITE PERSON'S FIST.. NO WAY NO HOW NO DAY ANYWAY SO.. GO AWAY!
BOTH of the white man's hands are MORE PALE than her fist, yet in deeper shadow area EVEN THOUGH HER SKIN TONE IS MANY SHADES MORE PALE THAN HIS!!!! Explain THAT one huh?
She is much more pale than the man, yet the man's hands appear more pale than her fist. Your 'shadow' theory DEBUNKED RIGHT HERE.
