title: How can I change ColorPrimaryDark for just one activity?
body: <p>I would like to change the color of ColorPrimaryDark for just one activity. How can I do this?</p>
  
  <p>I think go to the styles.xml and change this:</p>
  
  <pre><code>&lt;item name="colorPrimaryDark"&gt;@color/blue&lt;/item&gt;
  </code></pre>
  
  <p>But the problem is if I do this I change the color of all my activities and I just need to change the color of one activity.</p>
  
  <p>Thank you for your help!</p>
  
  <p>To be specific, this color is the color of the bar at the top of the app I mean above of <code>ActionBar</code>. I use Kotlin to do this.</p>
