Lol! I figured a plain white wall was as featureless as you could get for something to stare at while you mentally conjure code.

And since I’m in the office today (voluntarily!) there is literally a white wall to stare at above my monitors! But there is also a window slightly to the side, so my “staring blankly while totally thinking of something that will help the company” game is strong.

Dark mode is definitely the way to go though. I have three monitors and one phone in front of me, and 3/4 currently show a dark background in the application on them.
