I'm not sure I can help, for I have had similar experiences with definitions
of AUS colors.
My best guess is that the reduced melanin (or other dark pigment) is a
naturally occuring phenomenon, and that careful selection and line breeding
can make it "more pure." Hence, the degrees of color can range from very
red-orange all the way to pale yellow, and near albinism.
My chocolates have thrown reds (oranges?), from time-to-time, and seem to be
more colorful than other chocolates I have seen. It is possibly because they
are carrying a recessive gene for reduced dark pigment, and the dominant
dark gene has something less than 100% penetration. This could allow the
underlying red/yellow colors to bleed through a little bit.
Surely, someone on the list has studied this effect in AUS. Help!

"DEMOCRACY" is two wolves and a lamb voting on lunch.
"LIBERTY" is a well-armed lamb denying enforcement of the vote.
