title: How to change Ionic Button text color
body: <p>It may be silly question but I am not much familiar with ionic and css, so Can any one tell me how to change text color of the ionic button? </p>
  
  <pre><code>&lt;div class="bottom-button" margin text-center&gt;
       &lt;button ion-button color="energized"&gt;
         Register
       &lt;/button&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Here, Button color is yellow and text color is black. I want to change text color to white.</p>
