title: Add Image component to new gameobject
body: <p>I created a new game object:</p>
  
  <pre><code>GameObject newObject = new GameObject("ObjectName");
  newObject.AddComponent&lt;RectTransform&gt;();
  newObject.GetComponent&lt;RectTransform&gt;().sizeDelta = new Vector2(width, height);
  </code></pre>
  
  <p>I'm looking for a way to add an image (script) for color purposes.
  How can I do it?</p>
