title: Seaborn KDE Plots with Different Colors
body: <p>I want to create a plot using Seaborn Pairgrid and plot the KDE plots in different colors. When I plot the upper triangle and diagonal, it gives me the different colors I want. When I plot the lower diagonal, all the KDE plots are in the same color. Is there a way to get this to work using the KDE plots as shown on the bottom triangle? Below is the code used to produce the attached image. </p>
  
  <pre><code>test = sns.PairGrid(data[::1000], hue='label', palette="Set2", vars=['T1', 'Fl', 'T2', 'HF', 'LF', 'FW'], size=5, aspect=0.8)
  test.map_upper(plt.scatter)
  test.map_diag(sns.kdeplot)
  test.map_lower(sns.kdeplot, shade=True, shade_lowest=False) 
  </code></pre>
