[Tex/LaTex] Change beamer theme mid document

beamer

Is it possible to change beamer theme mid document or do you have to make two pdfs and stick them together?

Best Answer

beamer themes (main themes as well as color, font, inner and outer themes) may not be switched mid-document. However, it is possibe (though perhaps not always desirable) to change beamer's internal settings in accordance with a desired new theme. In the following example, I mimic a switch from the default settings to that of the "orchid" color theme.

\documentclass{beamer}

\begin{document}

\section{First}

\begin{frame}{First}
\begin{theorem}
Some text.
\end{theorem}
\end{frame}

\setbeamercolor{block title}{use=structure,fg=white,bg=structure.fg!75!black}
\setbeamercolor{block title alerted}{use=alerted text,fg=white,bg=alerted text.fg!75!black}
\setbeamercolor{block title example}{use=example text,fg=white,bg=example text.fg!75!black}

\setbeamercolor{block body}{parent=normal text,use=block title,bg=block title.bg!10!bg}
\setbeamercolor{block body alerted}{parent=normal text,use=block title alerted,bg=block title alerted.bg!10!bg}
\setbeamercolor{block body example}{parent=normal text,use=block title example,bg=block title example.bg!10!bg}

\section{Second}

\begin{frame}{Second}
\begin{theorem}
Some text.
\end{theorem}
\end{frame}

\end{document}
