Almost all were pink. I don't remember any that were white but sdome got whiter after a hard interval.
But some got redder after a hard interval
Some had a more brown tint, could have been because of moree exposure to the sun. BUt some turned red with too much exposure to the sun. One guy turned red whenever a certain girl walked by.
One guy looked almost green at the end of a race.
Oh, and by the way, thanks to my studies of anthropology I have learned that all humans came from Africa. So I always mark african-american on my applications.
Deal with it
