Just another thought breed to either animal and hope for a male that is homo for 1 gene and het for other and breed male back to mom and try for superpastel ivory....Dunno what it would look like but I would still go with pastel for now....
There is no such thing as a het for yellow belly nor pastel .I like the pastel ivories
