Burly looks nice. But in my first use i ran into this bug https://github.com/alphapapa/burly.el/issues/28 So, that’s not usable for me, sadly.

Yeah, I’ve started to notice the same for me. I use neovim and emacs at work. Many files I open are now rainbow puke. I’m sure some people find it useful. I personally use an lsp and treesitter mostly for automatic indentation.

I’m thinking about making a color scheme which uses one color besides the main foreground and uses font weight and slant for highlighting in 90% of cases, limiting color to spare, relevant places. I’m tired of every string, number etc. being colorized. Just looks cluttered imho.
