This extension is now deprecated. I have not been using this extension for years and I don't have time to maintain this project anymore.
I hope that someone will eventually fork and maintain a new repo.
gruvbox is heavily inspired by badwolf, jellybeans and solarized.
Designed as a bright theme with pastel 'retro groove' colors and light/dark mode switching in the way of solarized. The main focus when developing gruvbox is to keep colors easily distinguishable, contrast enough and still pleasant for the eyes.
