Beige is very doubtful.
How can this color be darker than khaki while it is khaki plus added sexlinked chocolate (extra dilution).
I think they might be het dun plus sexlinked choc.

In the "Beige" experiment the breeder can not pinpoint the genotype of his animals. He makes assumptions that may not be valid.
Only elaborate testbreeding could confirm the beige genotype.
