> I cannot stare more than a few minutes at a dark background color scheme I've struggled to find a perfect set of color themes my entire life, at least, that's what now it feels like. And at some point I realized, the smaller the palette, the fewer color variations there are, lesser the strain on the eye. Also, staring for a long time at the same - light or dark (it doesn't matter) color theme makes me feel tired. In the end, I settled on two different [customized] themes, based on base-16 color themes. My main tool, my editor of choice is Emacs. I spent most of my time in it. I'm typing this comment in Emacs, while I have HN opened in the adjacent window (still in Emacs). I use circadian.el, which allows me to set my themes based on the time of day. They switch automatically and I love that. Maybe try different color themes based on the light source, your mood, time of the day, place, etc.?
