i was just thinking that same thing yesterday! and then i thought it would be really cool if instead of a white tan, the tan part was black so it would be a white mouse with a black stomach haha. i think that would look awesome!
maybe you could get a broken tan with mostly white markings and just very minimal color?
i had a thick moment with one of my last litters, the Choc and Champagne pups were tanned, and i was shocked to see the PEW and BEWs not, then i almost slapped myself when i just realised what just went through my head :lol:
It would look very cool though!
