joshdick/onedark.vim
A dark Vim/Neovim color scheme for the GUI and 16/256/true-color terminals, based on FlatColor, with colors inspired by the excellent One Dark syntax theme for the Atom text editor. Install the theme using your Vim plug-in manager of choice (or manually, by placing colors/onedark.vim in your ~/.vim/colors/ directory and autoload/onedark.vim in your ~/.vim/autoload/ directory.)
