Well, for an extremely patterned snake like that, I would choose something that also affects pattern, like cinnamon. She could produce some amazing Savanahs.

Pastel is a good choice with her blushing, if you have a highly blushed pastel to breed her with, She could make some special Pastave's.

Or you could even use your butter, they might throw some very white BEL's.
