title: Set tick egde color in matplotlib rc
body: <p>I want to write a callable function that sets my matplotlib rc Parameters uniformly for all my different plots. So far it is just a block that I copy to every file and boils down to this:</p>
  
  <pre><code>import matplotlib as mpl
  
  grey = '#808080'
  
  mpl.rcParams['axes.linewidth'] = 0.3
  mpl.rcParams['axes.edgecolor'] = grey
  </code></pre>
  
  <p>I am doing this to have thinner axes and to make my data stick out by having everything else a little grey-ish. But I cannot find a way to set the tick edge color to grey in the rc. I am looking for something like </p>
  
  <pre><code>'axes.tickedgecolor'
  </code></pre>
  
  <p>which doesn't seem to exist, sadly.</p>
  
  <p>A way of doing it without rc is described here: <a href="https://stackoverflow.com/questions/7778954/elegantly-changing-the-color-of-a-plot-frame-in-matplotlib">Elegantly changing the color of a plot frame in matplotlib</a></p>
  
  <p>I hope somebody can help, thanks!</p>
  
  <p>Edit: Just to clarify: I found the option</p>
  
  <pre><code>mpl.rcParams['tick.color'] = '#808080'
  </code></pre>
  
  <p>but it also changes the tick labels, which I want to remain black!</p>
