It is just a variation on what you already have but Mom's Dad was always called "Pink." It was even embroidered on his firehouse jacket. I guess he didn't like his given name much, "Clarence". My mother was always "Little Red" and
her older sister was "Big Red". Those are the only coloring based nicknames we had on either side of my family, that I know of.

As a little kid playing in my grandparents' neighborhood it was always kind of strange. One of the adult neighbors that we didn't know would look at us and say "you're one of the ______kids, aren't you ?" And they always had the right name. It shocked us at the time. We didn't understand that we looked so unique that everybody with a few blocks could guess who we were just be looking at us.
