+
+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.
