How to nail the font size in the Run area & Does any theme have an absolute black background

1) Every time I execute a script, the Run output is microscopic. I always have to ctrl - scroll to get it so I can read it.

I tried ctrl-shift a but found nothing that appeared relevent. I'm running the Material Deep Ocean theme if that matters.

2) Is there a way to fix the Material Deep Ocean to give a #000000 background or is there another theme with absolute black?
