Here is the problem with that.
No one calls the Supers "Russos"
They are just called "White Diamonds"
Het Russo x Het Russo = White Diamond.
TECHNICALLY, you could call it a Russo... Or a Russo line Leucistic.
THAT is the only time someone calls it a Russo... when it is called a Russo line Leucistic aka White Diamond.
And it is a solid white blue eyed snake.
