  <em>current FAB</em></p>
  
  <p>I would like to know how to change the icon color of the FAB (Floating Action Button) widget supplied by the 'com.android.support:design:22.2.0' library from green to white.</p>
  
  <p><strong>style.xml</strong></p>
  
  <pre><code>&lt;resources&gt;
  &lt;style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"&gt;
      &lt;item name="colorPrimary"&gt;@color/color_primary&lt;/item&gt;
      &lt;item name="colorPrimaryDark"&gt;@color/color_primary_dark&lt;/item&gt;
      &lt;item name="colorAccent"&gt;@color/accent&lt;/item&gt;
  
  &lt;/style&gt;
  &lt;color name="color_primary"&gt;#00B33C&lt;/color&gt;
  &lt;color name="color_primary_dark"&gt;#006622&lt;/color&gt;
  &lt;color name="accent"&gt;#FFB366&lt;/color&gt;
  </code></pre>
