From my own observations, homozygous blue turns the brown/fawn in e+/e+ ducks (females) to a colour on the continuum between buff & apricot, maybe dependent to some degree on the phase gene involved?
Some examples:-
Apricot Fawn ducks are the wild-type colouration with two doses of blue & appear largely a creamy-buff (pastel) colour (with other hues also).
The Saxony is light phase wild-type with two doses of blue & appears colourwise buff.
The Appricot Runner (Dusky) is light phase dusky with two doses of blue & appears buff/apricot.
Others could be added to the list!
The Buff orpington is a little different in that it has the recessive sex-linked (illusive) buff gene. I have seen a photo of a buff orpington drake which apparently doesn't have any blue dilution but still appears buff. Genetically a dark phase dusky with a single dose of the blue gene here in Australia (plus brown & buff dilutions). I believe that elsewhere the buffs are bred with homozygous blue, these being termed blondes here.
Pure blue also appears to even the tone of pigmented areas (on a feather). For example, a Saxony is a trout & a trout ducks feathers a fawn ground with darker pencilling?
So, what has peoples experiences been with pure blue on e+ birds?
How has the blue affected the brown/fawn areas of the bird?
What is the difference in your view between buff & appricot?
How does pure blue appear when in combination with various genes, eg dark phase, light phase, harlequin phase , wild-type, dusky, restricted mallard?
Questions questions but would really appreciate hearing about others observations on the effect of pure blue on brown/fawn pigmentation
Cheers
