title: Box shadow color based on colors from image?
body: <p>Is it possible to have the <code>box-shadow</code> adjust its color value, based on the colors in the image it's being applied to?</p>
  
  <p>If you look at <a href="http://abduzeedo.com/tags/daily-inspiration" rel="nofollow noreferrer">abduzeedo's site</a>, you will notice that the images all have unique <code>box-shadow</code> colors, often related to their parent image (pictured below).</p>

  <p>I did notice that the CSS is being inserted in-line into the HTML, which says to me this is done through scripting, but how? Are these colors actually being pulled from their images or are they arbitrarily/manually generated?</p>
  
  <p>I've tried searching for this on Google, but I'm not having much luck.  I'm not asking for a tutorial, mostly just what this is called, how to find it, or if it's even possible to do it dynamically, rather than randomly or manually.</p>
