Just playing with the genetic wizard and I pulled up the black pastel/vanilla... it seems to look a lot like the snake does, only just a slight bit darker with the black. Unfortunately, I am having trouble finding a picture of a cinnamon/vanilla... I doubt I picked up a double codom cinnamon/vanilla for $60 but it's always fun to hope lol.
