title: Is there a way to change the built-in controlfx notification popup color?
body: <p>[Edit]
  here is an exemple of use of the <a href="https://controlsfx.bitbucket.io/org/controlsfx/control/Notifications.html" rel="nofollow noreferrer">notification popup</a> I'm talking about:</p>
  
  <pre><code>Notifications.create().title(...).text(...).hideAfter(Duration).show();
  </code></pre>
  
  <p>in this case the notification popup follow the modena style (a little bit gray)</p>
  
  <p>if we add dark style like this: </p>
  
  <pre><code>Notifications.create().darkStyle().title(...).text(...).hideAfter(Duration).show();
  </code></pre>
  
  <p>It's shown with dark color</p>
  
  <p>So I just want to know if there is a way to change these default style, I already know about the notification pane and I am not talking about it.</p>
  
  <p>So please I made my homework and did some research ... I found nothing that's why I here to find help</p>
