Applications :: Change Background Color Word 2011

I recently downloaded and installed Office 2011 and I was wondering if anybody knew of a way to change the background color from grey to anything you want. In 2008, there was a file in the Contents-->Resources folder called "Page Layout View Background Rest" that you could replace with any image and the background would change (by 'background', I mean the actual grey color on each side of the word document, not the background of the document itself).
