title: Seaborn chart colors are different than those specified by palette
body: <p>Why are seaborn chart colors different from the colors specified by the palette?</p>
  
  <p>The following two charts show the difference between the colors as they appear on a bar chart, and the colors as they appear in the palette plot. You can see if yo ulook carefully, that the colors on the bar chart are slightly less bright/saturated.</p>
  
  <p>Why are these different, and how can I get the bar chart to have the exact same colors as the ones specified in the palette?</p>
  
  <pre><code>import seaborn as sns
  sns.set(style="white")
  titanic = sns.load_dataset("titanic")
  
  colors = ["windows blue", "amber", "greyish", "faded green", "dusty 
  purple"]
  
  ax = sns.countplot(x="class", data=titanic, 
  palette=sns.xkcd_palette(colors))
  sns.palplot(sns.xkcd_palette(colors))
  </code></pre>
