Change the background color in a PDF viewer using embed, object, or iframe methods

Question

I played with various methods of displaying PDF files in order to find a way to change the gray background to white.

Here is a simple example of using object tags (I get the same result with embed and iframe tags):

<object data='https://dl.dropboxusercontent.com/u/58922976/test.pdf#view=FitH&scrollbar=0&toolbar=0&statusbar=0&messages=0&navpanes=0' type='application/pdf' width='84%' height='110px'> <p>It appears your Web browser is not configured to display PDF files. No worries, just <a href='https://dl.dropboxusercontent.com/u/58922976/test.pdf'>click here to download the PDF file.</a></p> </object> 

Thanks!!
