I will start by saying I am not a holland breeder and the breed I showed had only four colors but I do comment for judges and I have learned a lot showing rabbits.
Baby is not Himalayan and blue cream is not a recognized color. Your baby cannot be a full blue tort because that is a shaded color and shadeds do not have tan pattern. I think your baby is a Lynx and if I am right then the baby by now should be more blue and buff on the body. Lynx is an agouti color so when you blow into the coat it should have rings. If this baby does have rings and that black Tort in the same photo is it's sibling then be careful what colors you are breeding to. You can get unrecognized colors. This won't matter of course if you aren't showing. If you don't see rings then this baby is a blue tort with tan pattern markings which is unshowable and again won't matter unless you are showing
