I'd still like to know what the double het caramel + albino looks like. The general assumption is a normal looking double het from breeding caramel (aka caramel albino, aka xanthic) to an albino (aka regular albino) and that the double homozygous in the next generation would look like a regular albino.

But until proven otherwise we can't be sure caramel and albino aren't alleles and the double homozygous might look like a caramel.
