So here is Dusty. I think he might be a opaline DF violet DF grey YFT2. He also might be carrying cinnamon. Here is some background genes hope they help. His father is normal skyblue YFT2 carrying opaline and recessive pied . His mother is an Opaline DF violet cinnamon carrying recessive pied . He has a sister that is skyblue recessive pied YFT2. Here is a photo.
