If Marty is a Black Silkie she seems to have what they refer to as "leaking" a different color which I believe they say is a disqualification in show terms for Black Silkies.
But if she has both a gold collar plus gold speckled wing tips also she'd be classified a Dark Partridge ~ not a registered color for partridge yet cuz there's no established uniform standard but that's what breeders are calling them right now ~ not a popular variation I guess

. As far as I can tell they probably never will standardize them. I refer to them as "mutts" since they aren't a registered Silkie partridge color...
yet.

Our Mika is a Dark Partridge ~ a lot of her gold circular collar is hidden by her outer black feathers. She has to sit or move at a certain angle to see her gold collar. Same w/ her speckled wing tips too where the black body feather fluff covers the wing feathers. At 1st glance one might think she's all jet black... then she moves & the partridge shows.
DH isn't the best photographer w/ lighting or angles ~ he takes these w/ his cellphone.

DH is not the best picture taker but you can sort of see Mika's gold wing tips on her black body feathers? When she stands the gold collar disappears.

Again... not the best pic... Mika is the center chick moulting but if she moves just right her gold collar (hackles?) show.
