title: Change the background colour of YouTube Video embed
body: <p>I was wondering if there's any way to change the background-colour of the YouTube screen which appears when the embedded video is initially loading (image attached below)? Currently, it has a black background colour which I wanted to change to white; I tried adding <code>theme=light</code> to the URL but that didn't help. I also searched for this option inside the YouTube Embedded Players and Player Parameters document but couldn't find anything related to this. This is how my video embed code looks like:</p>
  
  <pre><code>&lt;iframe width="770" height="434" src="//www.youtube.com/embed/(video code)?theme=light&amp;modestbranding=1&amp;autohide=1&amp;showinfo=0&amp;controls=0&amp;rel=0&amp;vq=hd1080" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;
  </code></pre>
