Colour changing mouse? o.O

So I looked in on one of my colonies today and a mouse that was previously brown is not brown anymore? Not entirely at least. Very confused o_O





He was definitely solid brown when he went in to the tank, he's about 3 months old. I first noticed splotches about a month ago, thought he'd gotten dirty and didn't think much of it. But I saw him today during cleaning and was very surprised at the amount of black on him! (I also thought he was a she and there are babies in there now...woops...) I've never had any others change colour before, brown mice have stayed brown, although most of them get made snake food at a younger age than this...

Any idea's what gene might be causing this?

Doubt it. There have been no others in my lines yet, and I'm probably down in to my 8th-10th generations. The foundation stock was typical pet shop mice, broken blacks, doves and a tan/agouti (?) doe. I do get the odd random colour pop up every now and then, have a broken chocolate doe at the moment. I spoke to a person who has a colony of does all from me, and she said she's had a couple of mine change colour. One appeared brindle for a bit then went solid again, one went from a light tan to a very dark agouti!
