+same color as @code{\\thepagecolor}, except when the page background color is
+@code{none} (e.g., as a result of using the @code{\\nopagecolor} command).  In
+that case @code{\\thepagecolor} is @code{white} and @code{\\thepagecolornone}
+is @code{none}.  When @code{\\nopagecolor} is unknown or broken
+(@code{crop} package), this package provides a replacement.  Similar to @code{\\newgeometry}
+and @code{\\restoregeometry} of the @code{geometry} package @code{\\newpagecolor@{...@}} and
+@code{\\restorepagecolor} are provided.  For use with the @code{crop} package
+@code{\\backgroundpagecolor@{...@}} as well as @code{\\newbackgroundpagecolor@{...@}} and
