title: How to fill with a different color an area in seaborn.distplot
body: <p>Is it possible to fill with a color the area outside the two threshold lines (line1 and line2) and limited in Y-axis by the KDE curve drawn by distplot ?(that represents 3-sigmas for my application)</p>
  
  <pre><code>import pylab as pl
  import seaborn as sns
  #plotting the two lines
  p1 = pl.axvline(x=line1,color='#EF9A9A')
  p2 = pl.axvline(x=line2,color='#EF9A9A')
  #plotting the PDF
  sns.distplot(stat, hist=True,color='#388E3C')
  </code></pre>
