title: Custom theme interferes with snackbar background color
body: <p>Trying out the new Design Support Library, I added a snackbar; but unlike its main background, the text area is not colored with the default value of <code>#323232</code>. Instead, it looks <a href="http://imgur.com/MvVhQkS">like this</a>. It seems to take its color from the <code>android:background</code> value defined in the custom theme in my <code>styles.xml</code>, which goes like this:</p>
  
  <pre><code>&lt;style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"&gt;
      ...
      &lt;item name="android:background"&gt;#4f4f5e&lt;/item&gt;
      ...
  &lt;/style&gt;
  </code></pre>
  
  <p>If I try to forcefully color it with </p>
  
  <pre><code>View snackbarView = snackbar.getView(); 
  snackbarView.setBackgroundColor(Color.YELLOW);
  </code></pre>
  
  <p>it only impacts the main background, <a href="http://imgur.com/gvkd9i4">like this</a>, and the text background still gets colored by the custom theme. Is there a way to both keep my custom theme, and have a standard snackbar? Thanks!</p>
