Showing my age, but I worked for years in a dark room with a green screen terminal. I've long since made a habit of setting my terminals (regardless of OS) to exactly the same bright green on black. I do prefer the font bolded though. When I first started (rather shortly after--few years) CRT replacements became available for my favorite terminals. So if I wanted I could use either bright blue on black or bright red. Both surprisingly useful in darkened rooms!
