Synopses:
\pagecolor{name}
\pagecolor[color model]{color specification}
\nopagecolor
The first two set the background of the page, and all subsequent pages, to the color. For an explanation of the specification in the second form see Colored text. The third returns the background to normal, which is a transparent background. (If that is not supported use \pagecolor{white}, although that will make a white background rather than the default transparent background.)
