title: Animating color in Fabric.js
body: <p>Loving fabric and trying to get to grips with it all.</p>
  
  <p>First, I created a text like this:</p>
  
  <pre><code>newtext = new fabric.Text('EUI', {
      fontFamily: 'UbuntuL',
      fontSize: 70,
      fill: '#555',
      selectable: false,
  });
  canvas.add(newtext);
  </code></pre>
  
  <p>But, It can't change color with animate:</p>
  
  <pre><code>newtext.animate({
      fill:'#f00',
  }, {
      duration: 3000,
      easing: fabric.util.ease.easeOutCubic,
      onChange: canvas.renderAll.bind(canvas),
  });
  </code></pre>
  
  <p>Can someone explain please?</p>
  
  <p>Thanks</p>
