I recently created <a href="https://github.com/ezpieco/clarity.nvim" target="_blank" rel="noopener nofollow">clarity.nvim</a> because I found most neovim colorscheme a little too much, not saying they are bad though, they are pretty good, I use rose pine myself a lot actually, but they all have a tendency to highlight nearly everything, not I have no problem with that but it kinda ruins the whole point of highlighting things, that is, “Mark the important stuff” so keeping that in mind I just build clarity.
I’ve tried my best to highlight all important things, these being comments and definitions(hopefully).
You can also take a look at some of these examples here
