[enhancement] Request for pure black/dark theme

[MzeeAlii]

I prefer BN0021 and BN0032 models in black, of course. But I find the background color in dark styles is grey with some kind of a purple hue.

Even though it looks nice as it is, I can't help but wish there was an option for a totally black/dark style—call it triple black or double dark. With the mini LEDs on the new Mac model, I say it would look pretty sick.

Noted! I've been busy lately, but I'll add an option for this next time I work on it!
