Looking at myself in mirror

Cyclists have funny tan lines, at least this one does.  From my toes to my ankles I am white.  From my ankles to mid thigh I am dark brown, since my cycling shorts are three slightly different lengths there are three shades of brown at mid thigh. From mid thigh to my neck I am white. My arms are dark brown from shoulder to wrist, from wrist to first knuckle my hands are white and from first knuckle to finger tips light brown.
