Vim and Emacs colors

When I first started using `nvim', I copied my `nano' config which was very cringe and basic. And so I scoured the internet for themes. And discovered something truly disturbing: Every single `nvim' and `emacs' theme looks exactly the same, and they're all gray-on-gray cringe. I prefer my cringe to really pop rather than ooze before my eyes, so I somehow found the `nvim' theme that gradually became this.
