title: Changing color on dojo charting ThreeD theme
body: <p>I am displaying a graph using the ThreeD theme from dojo charting.
  When I modify the data so I can show a different color for certain
  bars in the graph, I lose the 3D look.</p>
  
  <p>Default color for ThreeD them is red</p>
  
  <p>{y:"15",tooltip: "15 Alarms",fill: 'yellow'}</p>
  
  <p>Adding 'fill: yellow' on the data item changes the bar to yellow,
  but I lose the 3D look.</p>
  
  <p>Any ideas on the best way to change the main theme color and keep 3d look??</p>
