title: How to change the line color in seaborn linear regression jointplot
body: <p>As described in the <a href="http://stanford.edu/~mwaskom/software/seaborn/generated/seaborn.jointplot.html" rel="noreferrer">seaborn API</a> the following code will produce a linear regression plot.</p>
  
  <pre><code>import numpy as np, pandas as pd; np.random.seed(0)
  import seaborn as sns; sns.set(style="white", color_codes=True)
  tips = sns.load_dataset("tips")
  g = sns.jointplot(x="total_bill", y="tip", data=tips, kind='reg')
  sns.plt.show()
  </code></pre>

  <p>However, with a lot of data points the regression line is not really visible anymore. How can I change its color? I could not find a builtin seaborn command.</p>
  
  <p>In case the line is in the background (i.e. behind the dots), I would also like to ask how to bring it to the front. </p>
