Looks like it has black eyes to me, so no it can't be champagne or argente. Without knowing its genetics you can't tell what it really is, my best guess is stone, but it could also be a pale red or other dilute. Beige isn't a real colour, so beware of this 'breeder' if you're planning to have this mouse as anything but a pet

Maybe I should have phrased that 'There is no such recognised colour as beige IN THE UK', which is where your breeder is located of course. Make sure you check they know what they're doing since they don't know their colours - if they are setting themselves up as very knowledgeable this is a clue that they're not. Since you might be breeding from this mouse you want to know you're getting it from the right person. Clearly it's a pet quality mouse, so be extra careful and enquire about illnesses in that line. If they can't tell you about the line past the parents then again beware. I'm not saying pet mice are terrible but I know I wouldn't breed from them myself.

I didn't say they were a bad breeder for not knowing their colours. I was trying to point out that there are lots of people who say they are 'experts' when they're not Clearly I don't know this person so can't say what they're like, it was a general point. As for them being just pet mice, if you're breeding them you still need to take a lot of things into consideration before you start or you might end up producing babies that are not what you wanted in terms of temperament, health, longevity and other things... it's too late once you've started!

If the breeder doesn't know anything about its history then no, you can only guess or test breed.
