title: How to change background color of youtube Player - youtube-iframe-api
body: <p>When start playing my video on my website <a href="http://jaideeppackers.in" rel="nofollow">jaideeppackers.in</a> there are black colour strips shown by the YouTube player on right and left.</p>
  
  <p>I want to set it to white so that it merges with the background of my website. </p>
  
  <p>It has nothing to do with option <code>theme=light</code> and <code>theme=dark</code>, so any other way to achieve this?</p>
