Change bookmark & content pane background

[JGaf]

Hi,

Is there a way to change the bookmark & content pane's background?  I'm looking to change it to black (from the default gray).   

I've attached an example of what I would like to do  (the bookmark text is partially covered for privacy).  I've clicked around in preferences and settings and haven't been able to find anything but how to change the PAGE background color, which isn't what I want to do.

I have Adobe Acrobat PRO DC (Classic, 2015.006.30527)

tia!
