Let me just say, there are no rare colors of Great Danes - only correct and incorrect colors and markings.
Some breeders will try to pass off their incorrect colours/markings as hard to find, rare,special and even designer colours. Remember correct or incorrect. Period.
It is my belief that breeders should not purposely produce incorrect colors, every breeders goal should be to produce the most correct Great Dane possible, this includes color.
Only the following 6 colours can be bred from and shown (registered on Main registration)
