title: Matplotlib: How to unset default colormap?
body: <p>I am showing images with matplotlib and applying some colormaps to the images. I've figured you can set a default colormap by something like</p>
  
  <pre><code>plt.set_cmap('jet')
  </code></pre>
  
  <p>and then that colormap will be applied every time when using <code>plt.imshow()</code></p>
  
  <p>But how about undoing that? If I want to show the original images again without any colormap? I haven't found in the docs anything about that, neither by quick googling so any help would be appreciated.</p>
  
  <p>Thanks!</p>
