The idea is that if everything is highlighted then your brain adapts and stops paying as much attention to highlighted elements. Many colorschemes use too much colors. It is not uncommon to have one line be highlighted with red because of an asynchronous linter warning, and many other words with purple because they are keywords like 'class', 'def', 'do', 'end', and so on. And there are a bunch of other colors everywhere else. Some people ask themselves "Do I really want to highlight syntax elements? If there is a syntax mistake, my editor will immediately tell me anyway, and it will be much more prominent if I have a clean uniform sheet of code." I've been using minimalist colorscheme for more than a year now. To me it highlights only what matters: mistakes are red, code is dark and uniform, comments are faded, current line is highlighted, search matches have their own color. That's it for the most part. There are some subtleties that are also handled. Minimal highlighting is beautiful and clean. Too much color is ugly and messy. Just become clean! Remove your wallpaper, remove those tiny ugly icons from your toolbar, find minimal colorscheme, install tiling window manager, take a bath.
