I've known a few Chinese and Koreans who have turned from snow white to really dark in a matter of a week just from being exposed to the sun. I also have a few Irish friends who just burn to a crisp and never seem to get a tan. I've turned a bit darker over the years but the bits that don't get exposed to the sun show my original shade.
