title: change background color in zsh (ubuntu 12.04)
body: <p>I installed the zsh package. So, now when I type <code>zsh</code> in terminal it switches from bash to zsh.</p>
  
  <p>Also, I downloaded the <a href="https://github.com/robbyrussell/oh-my-zsh/" rel="nofollow">oh-my-zsh</a> framework to customize zsh. When I change theme name in <code>.zshrc</code> file to one of the themes given <a href="https://github.com/robbyrussell/oh-my-zsh/wiki/Themes" rel="nofollow">here</a>, it changes the color/type of prompt among other things but the background color stays the same. I want the background color to change to the ones given on that theme wiki page. </p>
  
  <p>So, how do I do change the background color automatically to the ones on that page whenever I change my theme?</p>
