If she is for sure pure bred then The white markings would indicate she is a vienna marked rabbit. This gene comes from Blue Eyed White rabbits. If she is mixed then it could indicate she has a dutch ancestor but by the looks of her and how little white she has i would say she is vienna marked.
As far as the tort color maybe shes a blue or lilac? If she is under 6months then she still might have to shed her junior coat
