Hello, welcome on your potential new arrival. How old are the puppies?
I have one of each - a black & white ticked and a light blue roan. There is a thread on here if you search where there is a discussion around how can you tell the difference and pictures have been posted. Breeders can normally tell early on if the puppies are blue roans or black & white ticked.
With my boys Charlie was definitely black & white ticked, he had pretty pink paw pads as a puppy that have darkened over time, but he was white with black patches and the ticking became more evident over a few months. Dexter was definitely a roan, when I picked him at 6 weeks his paw pads were black, he had visible roan on his legs, face and a little on his back, his roan has darkened over time.
