I'd forgotten what Mr P looks like without the pullet grooming salon effect!
That pic just struck me....I think I have him at least somewhat figured out!
That info about silver affecting red. That's why he had the blonde look. His silver is covering the red which is bleeding through as straw/lemon (the lemon color may have more than just the silver going on). He throws orange Creamsicle offspring. (Other factors lighten the red to the creamsicle). They got the red color and not the silver from him.
Now the white.....he throws a lot of blue chicks, so he's got splash (affects black), but he doesn't have enough "fingerprints" ....unless he's splash AND Dominate white? (If both can be on the same bird, empirical evidence strongly suggests this).
Strip off all his white and he's classic black breasted red, if heavily modified......
I think.....
