Actually, Carolyn, PPP is a black in my book - same interior color, green seed gel, etc - only missing the dark shoulders - so much darker/duskier in color than the true pinks such as EPB and Ginny's Purple. PPP has the chlorophyll retention gene that ChP, Price's Purple, etc possesses -the only difference is that the cross with Ozark Pink gets rid of the non ripening shoulders. I like the description in this thread that PPP is uniformly the color of the blossom end of Cherokee Purple.
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.
