title: Oh My ZSH theme not matching colors
body: <p>I'm trying to make this zsh theme work: <a href="https://gist.github.com/3712874" rel="nofollow noreferrer">https://gist.github.com/3712874</a></p>
  
  <p>I've made some small changes to it but there is still one problem. It seems that the right triangle glyph doesn't get the same color as the text background. See this image:</p>

  <p>Any ideas why this might happen, and how to fix it?</p>
