My parts are all the same color...cock and balls are both a matching shade of light tan. But i have been with guys (and there are several in the gallery) who have dark, dark balls, but a light colored cock. Also, there are some cut guys who have a dark brown shaft below their circumcision scar and very light pink color on the top of the shaft and head. I'm circumcised, and it is all one color. Not sure why i'm even bringing it up...just observing.... what are your colors?
