title: Color display issue with oh-my-zsh agnoster theme
body: <p>I have set up oh-my-zsh on RHEL machine running red-hat and I am using agnoster theme. But there seems to be some problem and on terminal the things are not properly displayed. Below is how it is displayed:</p>
  
  <p>{black}{default} adarshs@adarshs {blue}{black}⮀{black} ~/.oh-my-zsh {yellow}{blue}⮀{black} ⭠ master± {yellow}⮀</p>
  
  <p>It seems to me that there is some issue with the color scheme. </p>
