Female mama Mouse

Husband and daughter own snakes. A friend who raises snakes and mice gave us our own starters for feeder mice. Well, we have bonded with some of them, so there you go...You can't feed a pet to another pet. That's just sick. She has babies by a PEW. Her coloring is quite a bit lighter than this picture shows. She's more silvery/pale on her sides, and is almost white underneath. She has darker brindles or variegation, I don't know which because I'm no expert. She had a litter of 11 of which 10 are alive and 4 weeks old. Thank heavens more cages are coming tomorrow. Can anybody give me a guess to what color she is considered. I'll upload some more pics of her and her babies too. We just call her Mama Mouse or Lady Mouse for now, until we decide on a name.
