But I think the problem/hardship lays in the natural saturation of reds in balls isn't that high to begin with.
Also, a snow is an albino and axanthic, two genes that STRIP red coloring. You'd be working against the gene's trying to make it redder.
There isn't a "proven" gene out there that stripes just black and yellow besides the the toffee ball that VPI is working with.
I think THAT gene could potentially be worked to making a high contrast red animal, but I can't see it being done very well with any morph genes out their now, since almost all of them strip red and yellow, or red and black together.
Now the burgundy is supposedly a proven line, I can see that being worked with, and perhaps crossed into the toffee line to create a fantastically red animal.![]()
