One of the things I enjoy is setting up my development environment to look just the way I like it. When looking around for a good color theme for my code editor, I found gruvbox, and quite liked it. But the theme's contrasts were still a bit too sharp for my taste, so I decided to make my own, plainer variant: gruvbox-plain. Over the course of my programming projects, I've kept improving the theme's support for various syntaxes, and even made two different variants.
