Putty definitely requires you to edit its default settings, but I was in general really surprised at the level of control you have (on a Windows application).
Side note: Am I in the minority for disliking how Solarized looks? It's so damn popular but I really can't seem to find its appeal.
Voice for Solarized: I use it everywhere, because it’s popular, consistent, and not horrible to look at. This means I can have essentially the same color scheme everywhere, which is nice, plus the light/dark themes are very easy to make (which, conveniently, reduces the amount of syntax highlighting CSS on my website quite a bit: the only thing I need to have “dark mode” is changing the background color). I’m not completely sold on the “algorithmically perfected, better for your eyes, etc.” stuff but I do think it’s not horrible, which is not a guarantee I can make about $DEFAULT_COLOR_SCHEME_FOR_RANDOM_EDITOR.
I'm not a fan of Solarized either, but really like Gruvbox. It is somewhat similar to Solarized, but with plenty of contrast and a not-blue dark background.
But looking back at Solarized, I can't see why I used to dislike it so much (low contrast) - perhaps it's because I now have a HiDPI screen which can more precisely render the text apart from the background?
I used to use Solarized everywhere, and it's still my fallback. I like its consistent colours, and I use the darker colours as my wallpaper on my desktop/laptop.
I've switched to using One Dark in my editors though, it feels slightly easier on my (aging!) eyes.
A lot of people use Solarized, I think, because they are not happy with the defaults, and Solarized is very well put together. So when people see the new colours available to them, they think "this is great! I should use this everywhere!" and thus it gets potentially way overused.
