That's something I want to learn about.
Is there anyway of predicting the possibilities or is it down to chance.
I'd like to get some shetlands and have lots of different colours for spinning.

It's less chance, more ancestry and genetics, but you need to know the colours of every ancestor stretching back forever, then it's an educated guess as to which combination a particular lamb will inherit. They are talking of putting some better explanations on the Shetland website to help inexperienced owners with identifying colours. Apparently the colours given on the registration info are not exhaustive.
I can understand simple heredity, and a bit of Agouti, spotting gene, modifiers and so on, but beyond that it gets just too complicated. I can't help but wonder too if the birth colour doesn't change after the first shearing, so you've registered your moggetfaced, krunet, sokket, blue lamb, only to find that it's blotchy grey next year
