title: How to change header background color in react based on location
body: <p>How do I change my headers color based on what route/page I am on in my React project?<br>
  I have looked at <code>withRouter</code> but I am not sure how to use the example.<br>
  I just want to do something like if the route is not the Home component then change the background color of the header to blue.  Seems like it would be simple but can't figure it out.    </p>
