Prevent blinding white screen

[ThreeDeeJay]

There's a brief flash of a retina-burning white screen when opening some apps at night, and I'd very much love to Thanos-snap it out of existence. IIRC it may happen even in apps where DarQ is darkening the UI as usual.

There's got to be a place where #FFFFFF is set as the default background, right? Maybe I could edit that with root but I can't find any info on that. Or is that just the default "empty" color?
