Not Springers, but Cockers, I have a liver and white puppy, and her eyes really are orange. I've a sheepdog who's basically black, and his eyes are yellow. I've two black cocker puppies, and one has lovely eyes, rather like Zak's, and the other one has eyes which are virtually black.
I suspect that dogs, like humans, have their hair or skin colour influencing the colour of their eyes, but not always.
