I started on monochrome dark screens with white, green or orange phosphors. When I first started (briefly) using a Lisa in 1983 and then a Macintosh in 1984 I found that I really liked the paper-white look. Eventually I decided that I preferred that the theme match the ambient lighting conditions. The recent operating system and browser features to provide adaptive behaviour is exactly what I sought. I now use light themes during the day–I am also a fan of natural light, and dark themes at night with reduced blue and lower colour saturation. I personally don't understand the preference for dark themes in bright ambient lighting. For me it seems to induce more eyestrain than relieving it.
