title: How to get default behaviour of ng-disabled using my own colors palette in Angular Material with AngularJS 1.x?
body: <p>I'm using my own colors palette to set some special colors in some buttons in a section of my app. So, when I use the default palete and <code>md-primary</code> for example if I set <code>ng-disabled=true</code> the button become not clickable and the color is setted of gray. The problem is when I use myown palette, if I use <code>ng-disabled=true</code> I can't push the button but the color doesn't change and I would like that this happens.</p>
  
  <p>This is an example of use:</p>
  
  <pre><code>&lt;md-button
          ng-disabled="true"
          ng-click="..."
          class="md-icon-button"&gt;
      &lt;md-icon ng-if="..." md-colors="{'color': 'specialpalette-pastelGreen'}" &gt;
          check_circle
      &lt;/md-icon&gt;
      &lt;md-icon ng-if="..." md-colors="{'color': 'specialpalette-pastelRed'}"&gt;
          cancel
      &lt;/md-icon&gt;
  &lt;/md-button&gt;
  </code></pre>
