Description
The attached PDF's header is shown in brown instead of grey (when compared to adobe). This is a minor issue but can be important where branding is concerned.

The file in question uses a CMYK color model which needs to be converted to RGB for screen display. The algorithm that does this conversion generally does a good job but tends to be a little darker when compared to Acrobat. However the file in question is using a CMYK colour value that only specifies a black value (Y) and thus can be treated at a gray colour space.
Once this adjustment is made the our DeviceCMYK colour space the PDF matches Acrobat exactly.

I need to run the change through QA but don't expect any problems. The rendering core should do a better job at converting black only CMYK values to RGB.
