Your doe is Vienna marked, your buck is REW. Do you have any information about the colors of their parents?
There are many different genes in many different locations in the rabbit genetic code that influence coat color. REW occurs on the C locus. Since it shuts down all pigment production to the coat, there is no telling what other genes the buck is carrying just by looking at him. He might even be carrying BEW, you can't tell by looking. The only thing you know for sure about your buck, color-wise, is that he had 2 REW genes, so all of his offspring will get one from him.
Your doe is Vienna marked, so you know she carries one BEW gene and one not-BEW gene at that location. Some of her offspring will get a BEW gene from her, some won't. Her color indicates that she has non-extension genes(e) at the E locus, and it looks like self genes(a) at the A locus (I'm thinking Tort rather than Orange). Both e and a are recessive, though the doe will be giving them to all of her offspring, whether you'll see them depends on the buck's contribution.
If you get any REW babies, you'll know the doe carries an REW gene. If you get Siamese Sable, Himi, or Chinchilla babies, you'll know that came from the doe. If you get any BEW babies, you'll know that the buck carries BEW. Because the doe has self at the A locus, if you get Agouti or Tan colors, you'll know that came from the buck. If you get Tort, Orange, or Sable Point, you'll know that the buck has at least one non-extension gene, if you get anything darker, it's because he has a full extension or maybe even steel gene.
Basically, going only on the colors of this pair, there isn't enough information to say what your outcomes could be. On the other hand, the babies could tell you a lot about the parents!
