Icon Text Backgound Colors.

Is there a way to make the backgroud of the text on desktop icons transparent or if not what is the simplest way to make the changes to a different color.

An example of what I'm wanting to do I did it photoshop here...

Thanks a lot that worked but another problem appeared...how can I make the text stay black.  It all changes to white which doesn't work with the background.
