So, to me, a "black" variety are those pinks and reds that retain some chlorophyll - aka green - colors as they ripen....giving them a much deeper hued interior. A clear skinned black being a purple, a yellow skinned black being a chocolate or brown.

Craig, I'm not so much concerned with the interior color of PPP altho there's a cut slice in the picture in my book and it isn't dark at all, I'm concerned with the exterior color.
I agree that the interior color of a TRUE black should be a darker color with greenish seed capsules but that's not what I saw with PPP, viz the picture I referred to.
I see a clear skinned black being pink/black as I've said before and that would refer to varieties such as Cherokee Purple, Black from Tula, Indian Stripe, etc., and yellow skinned black being what I call a red/black such as Black Krim. Carbon, and the like.
It's no fun if we agreed on everything.
