title: Discrete Bar Chart colors nvd3.js
body: <p>I am using nvd3.js discrete bar <a href="http://nvd3.org/ghpages/discreteBar.html" rel="noreferrer">http://nvd3.org/ghpages/discreteBar.html</a></p>
  
  <p>I am inspecting the code and seen that the color is been derived inline</p>
  
  <pre><code>style="fill: #ffbb78; stroke: #ffbb78;"
  </code></pre>
  
  <p>I also track on the discreteBarChart function</p>
  
  <pre><code>color = nv.utils.getColor()
  </code></pre>
  
  <p>What I don't realizing and asking is what does color takes as a parameter ?</p>
