# Is there a package for turning a beamer presentation into a grey scale presentation?

I have a beamer presentation in latex where I want to turn the colors into grayscale colors. It includes some graphics and text in various colors, and I want to eliminate this. Is there a way to just include a package and turn a given document/presentation to be black and white?

Pass the option gray to the package xcolor

\PassOptionsToPackage{gray}{xcolor}
\documentclass{beamer}


EDIT:

blackandwhite wrote that it doesn't have any effect. Here is a full minimal working example which works well:

\PassOptionsToPackage{gray}{xcolor}
\documentclass{beamer}
\usetheme{CambridgeUS}
\begin{document}
\section{Abschnitt Nr.2}
\subsection{Listen I}
\begin{frame}\frametitle{Aufz\"ahlung}
\begin{itemize}
\item Einf\"uhrungskurs in \LaTeX
\item Kurs 2
\item Seminararbeiten und Pr\"asentationen mit \LaTeX
\item Die Beamerclass
\end{itemize}
\end{frame}

\begin{frame}\frametitle{Aufz\"ahlung mit Pausen}
\begin{itemize}
\item Einf\"uhrungskurs in \LaTeX \pause
\item Kurs 2 \pause
\item Seminararbeiten und Pr\"asentationen mit \LaTeX \pause
\item Die Beamerclass
\end{itemize}
\end{frame}
\end{document}

@blackandwhite Do you mean you have external graphic files (.png, .jpg, etc) in colour, and they're not coming out as grayscale? AFAIK the only way to get them in B&W is to edit them in an external image editing program. – LianTze Lim Sep 24 '11 at 8:07
thanks, seems to work now. – blackandwhite Sep 26 '11 at 14:34

If you're just looking to change the color of text, header, footer and background, several of the default themes are b/w and grayscale.

\usecolortheme{beetle}
\usecolortheme{dove}
\usecolortheme{fly}
\usecolortheme{seagull}
\usecolortheme{structure}


These will result in remarkably different amounts of black vs. white with different themes. For example, try any (one) of the above with any (one) of the following.

\usetheme{Berkeley}
\usetheme{Hannover}
