title: Shell command to get color under mouse cursor (xorg)
body: <p>I need to get the color in hex code of the pixel beneath my mouse cursor. There are plenty fancy GUI-tools to solve this task, but I need a <em>simple</em> command line way to get the color, so that I can use the solution in a shell script.</p>
  
  <p>Possibly I could use ImageMagick to take a (one pixel?) screenshot and extract the color from it (I can fetch the position using <code>xdotool</code>)). Maybe there is a simpler solution.</p>
  
  <p>Any suggestions?</p>
