title: How to convert hex to Color(RGBA) with TryParseHtmlString
body: <p>How can I change the button color in Unity, using HEX values?<br>
  I tried this, but it doesn't work, perhaps I made a mistake here:</p>
  
  <pre><code>btn.image.color = ColorUtility.TryParseHtmlString(DADADAFF, out color); 
  </code></pre>
