      " Use 24-bit (true-color) mode in Vim/Neovim when outside tmux or screen.
      " If you're using tmux version 2.2 or later, you can remove the outermost $TMUX
      " check and use tmux's 24-bit color support
      " ( for more information.)
      if empty($TMUX) && empty($STY)
        " See
        if $COLORTERM =~# 'truecolor' || $COLORTERM =~# '24bit'
          if has('termguicolors')
            " See :help xterm-true-color
            if $TERM =~# '^screen'
              let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
              let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"

    • To use 256-color mode, set your $TERM as *-256color or add set t_Co=256 in your .vimrc.
