This photo of mine is not to judge the faults in these birds but reference of color. This dark gold is what the standard calls for- True Partridge.
My own preference would be a shade lighter to make the penciling really POP and that is accepted if you don't let it go too light. I'll likely keep them as close to this tone of gold as I can so as not to lose it. I think they look quite regal this dark, the cocks have mahogany hackle and saddle. It's quite nice but do like the copper color better. Again, it's preference and personally am sticking with the standard.
