Paph Lynleigh Koopowitz - Black patches on leaves

[signin1234]

To me most of it does look like it's pigment. As far as owning both parents, my question would be is one of the parents of this cross a "dunkel" P. delenatii and is that what you also grow? I ask because the dunkel form of P. delenatii definitely has varying degrees of very dark almost black pigment on the upper side of the leaves in pretty much this same pattern.

The only thing that gives me slight pause is the way some of the pigment looks a little diffused on that one leaf with the most dark markings on it.

Delenati var dunkel was not called out as the parent but the darkening on the foliage of that variety sure looks a lot like this, thank you.

I wonder if the dark pigment is a reaction to high light conditions as the lower leaves do not have any of those markings...

Generally with P. delenatii dunkel, the lower leaves have much less or even no pigmentation on top aside from the margins. It's typically the newest top leaves that develop additional pigmentation beyond the leaf margins/edges and it fades over time. It can be related to higher light levels, but it seems/seemed to me that it was more of a variable individual trait. Some plants will simply have more pigmentation than others.
