title: Ionic button color change for specific button
body: <p>I have multiple buttons like this</p>
  
  <pre><code>&lt;button id="1" ion-button [color]="btnColor" (click)="btnActivate()"&gt;text&lt;/button&gt;
  &lt;button id="2" ion-button [color]="btnColor" (click)="btnActivate()"&gt;text&lt;/button&gt;
  //etc..
  
  
  
  btnColor: string = 'dark';
  
  btnActivate() {
    this.btnColor = 'secondary';
  }
  </code></pre>
  
  <p>When user click on any button the color change for <strong>all buttons</strong>. What I want is change the color attribute for the <strong>clicked button only</strong> or change <strong>based on ID</strong> of the button.</p>
