The doe is a Smoke Pearl, the buck is a Siamese Sable. These are both shaded colors. To be shaded like this, they must be carrying one shaded gene, and either one REW gene OR one Himi gene. An animal with two shaded genes is a Seal, which is very, very dark brown, so dark it almost looks black (until you set it beside a genuine Black!) If bred together, they can produce:
REW or Himi (Pointed White)
The doe is homozygous for the dilution gene. If the buck also carries it, they could produce:
Well, yes, but it isn't as bad as it may seem. I have seen rabbit coat color genetics explained in quite a few books, including a few that have it as their only subject. After a while, you learn to say, I'm seeing this, it's caused by this gene, etc, but sometimes you still get surprises. Pedigrees can be very helpful for telling you what recessives may be lurking behind the colors that you see.
Sometimes you forget things, too. For example, I forgot to mention that both of your rabbits might very likely be carrying (but not expressing) non-extension genes (some of the non-extension colors are very common!) So, there is a possibility that you could get Sable Point/Pearl Point, too!
