I use iTerm2+zsh+oh-my-zsh. Recently I wished to change the dark theme to a ligher one.

The command I ended up using: PROMPT='%{$fg[green]%}%~%{$fg_bold[blue]%}$(git_prompt_info)%{$reset_color%} '

Few super useful links that I came across

• https://stackoverflow.com/a/2534676/2806163 That is, to add

    autoload -U colors && colors
  PS1="%{$fg[red]%}%n%{$reset_color%}@%{$fg[blue]%}%m %{$fg[yellow]%}%~ %{$reset_color%}%% "
  

  in .zshrc (though I just did it on terminal to test)
