Take look at the classifieds section.

Here you wil find an ad where it says that someone has produced "miami yellow Leucistics".

Just for info, if they exist, they have a defect to their melanophores (dark pigment) and their xanthophores (red, yellow, orange pigment)
They can't produce dark, red yellow and orange color.

I know, putting a name on them will probably make them sell much faster right?....or maybe it is a homework issue?
