title: Change background color of floating action button using my image palette
body: <p>Here is my code that I have used to retrieve color from palette. I am able to get the color but unable to set as background color of floating action button.</p>
  
  <pre><code>Palette.Swatch vibrantSwatch = palette.getDarkVibrantSwatch();
  Palette.Swatch vibrantSwatch2 = palette.getLightVibrantSwatch();
  
  if ( vibrantSwatch != null &amp;&amp; vibrantSwatch2 != null) {
      //fb represents my floating action button
      fb.setBackgroundTintList(ColorStateList.valueOf(vibrantSwatch2.getRgb()));
  }
  </code></pre>
