title: Color Themes in Google Charts
body: <p>I am pretty familiar with Google Charts but was never able to find one thing. You can change the colors of your columns or bars or pie pieces or whatever in a couple of ways but essentially it comes down to something like this:</p>
  
  <pre><code>chart.draw(data, {
    width: 400,
    height: 240,
    title: 'Toppings I Like On My Pizza',
    colors: ['#e0440e', '#e6693e', '#ec8f6e', '#f3b49f', '#f6c7b6'],
    is3D: true
  });
  </code></pre>
  
  <p>Does anyone know how I can apply a "color theme"? Meaning, make the chart all bluish, or reddish or orangish. The hard coded color values work OK if you have a fixed data set but I am working on dynamic data sets. Sometimes I will have 3 series and sometimes 15, and I would like a way to set a chart color style/theme.</p>
