title: Google chart - get color for row
body: <p>I have a Pie chart with lots of elements.
  I've left the color picking to google charts, but after the chart is drawn, I need to retrieve the color of each row.</p>
  
  <p>I know that I could generate the colors array, and set it in the charts options, and that would solve my problem, I would be able to retrieve the colors from there. But I really don't want to create that big array by hand.</p>
  
  <p>So is there a way to get the color for a given row?</p>
  
  <p>Thanks!</p>
