# [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?

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 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}
