title: AngularJS Material Design : Different colors for different tabs in md-tabs
body: <p>Is there a way to set different background colors for different tabs in <code>md-tabs</code> ?
  The default is no color as can be seen in <a href="https://material.angularjs.org/latest/#/demo/material.components.tabs" rel="nofollow">tabs demo</a></p>
  
  <p>I tried <code>&lt;md-tabs background-color="green"&gt;</code> but it's not working</p>
