The following TeX code is intended to change the background color of an external pdf file by using the pdfpages package, but it does not work for me. Does it work at all?
\documentclass{minimal}
\usepackage{xcolor}
\pagecolor[HTML]{B0A030}
\usepackage{pdfpages}
\begin{document}
\includepdf[fitpaper,pages=-]{external/notes.pdf}
\end{document}
notes.pdfsomewhere for people to download and experiment with. Try FileDropper or DropBox. – Werner Dec 26 '11 at 21:50
