in some cases ressesive white can be comined with dominate to produ a color similar to what you have discribed.There seem to be some other factors at work with the Wheaton Cubalaya . Saladin and others have produced a "white" recessive from BBR Wheaton Cubalayas that when crossed back into the Wheaton BBR eventually produce Pyle. At least that is how he and Dave K explained it to me. The White recessives are not pure white, but have faint red /yellow hackles, saddles and wing bows in the cocks. The hens have faint red/yellow showing through on their breasts and in other places. I have two, a Hen and a Cockerel, same BBR X Brown Red parents different hatches. Unfortunately my camera is not of a good enough quality to show the red shading. To me they look like extremely washed out Pyles. A few pages back I posted a picture of a BBR cockerel , his mother is one of those "whites". If you wish you can see him in one of my albums. He will be bred to a Pyle hen next spring, we shall see what happens. I am not trying to dispute what has been stated , just adding to it. Perhaps Saladin and or Dave K will jump in and give us the benefit of experience. I have been keeping poultry farm flocks for some 60 years, but only recently started breeding to the Standard after retiring from raising/ breeding/ showing/ purebred dogs, so not an expert on chicken genetics. .
p.s. good luck with those offspring
