Male is considered an agouti, or the 'wild type'. Depending on the genetics for each mouse, since they could have recessive genes and what not, you have the possibility for more agoutis, blacks, ad possibly albinos. However, that's just with the genes expressed. http://www.thefunmouse.com/varieties/index.cfm is a handy website for looking at mouse colors. Just don't post on their forum, they poo poo people like us who reed mice to feed our snakes.
