[souffle]

She does look to be a tortoiseshell and white. She can't be a smoke pearl tort though as smoke pearl is the yellow patches in a dark grey tort.
She must be either a dark grey tort or a silver grey tort.
If she is carrying something like cinnamon she may also have a more orangy colour cast to the coat.
It is hard to tell from pics though and also she still has a baby coat which will change to the adult colour around 10-12 weeks or even later.
