I actually went back to a light gray theme for my new Linux machine after I've been stuck with Windows's options of "flat pure black with hairlines" and "flat bright white with hairlines" for too long.
I don't actually need dark mode that much (except for coding) if a bright mode theme is easy enough on the eyes. Windows 10 is just so ugly that only the dark mode is halfway palatable.
If only the old themexp.dll hacks still worked I could have a decent looking desktop on all of my machines...
Not even very surprising. The dark and/or broody scenes tend to be a lot less serious than they look. To give an example I saw: At last year's Wave Gotik Treffen (a huge goth event) there were plenty of posters for broody bands – and in between them there was one for the German Hevisaurus spinoff advertising their new song about bubblegum.
And then someone went around and put googly eyes on all the posters. That's also pretty on-brand for the scene.
