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…
