Better pic of my favorite

Hi guys,
I finally got a better pic of my favorite rat, Buttercup. I am hoping that she will be the mother of my future breeders. I paired her with my black variegated male for 12 days, so am hoping she is pregnant.

I've gotten opinions from a couple folks and some think she is a Russian blue. I am still on the fence myself, but would love it if she was because that is a rarer color here. I am hoping to reproduce her color (probably in the second generation).

I will try and get more pics of the others up as well. The cage I now have the girls in makes it a lot easier to take pics.
