title: Change text color based on brightness of the covered background area?
body: <p>I am looking for a plugin or technique that changes a text's color or switches between predefined images/icons depending on the average brightness of the covered pixels of its parent's background-image or -color.</p>
  <p>If the covered area of it's background is rather dark, make the text white or switch the icons.</p>
  <p>Additionally, it'd be great if the script would notice if the parent has no defined background-color or -image and then continue to search for the nearest (from parent element to its parent element..).</p>
  <p>What do you think, know about this idea? Is there something similar out there already? Examples?</p>
