User @BATLABOR posted a method to have a “Light UI” in the following thread.
There is a screen shot in Post #2 and a PasteBin link to the code MOD’s in Post #4
I would not be surprised if more “UI Themes” come as part of Pinegrow 3, in addition to hopefully overall UI/UX improvements.
But if you want to fiddle around in the meantime maybe check that out.
