Document Classes ⇒ beamer | Change Color of Theorem Block

[omer21]

How can I change the background colors at 1 and 2 in the attached picture.

Thanks.

Theorems use the block title and block body colors. You can change it via \setbeamercolor, for example:

Code: Select all

\documentclass{beamer}
\usetheme{Madrid}
\setbeamercolor{block title}{use=structure,fg=white,bg=red!75!black}
\setbeamercolor{block body}{use=structure,fg=black,bg=red!20!white}
\begin{document}
\begin{frame}
\begin{theorem}
Text
\end{theorem}
\end{frame}
\end{document}

Thank you Mr. Stefan, it works.

...and how is possible to change the block body in only one or two frames?

You could call \setbeamercolor just in that frame, so the change is local and not in effect at the next frame:

Code: Select all

\begin{frame}
  \setbeamercolor{block title}{use=structure,fg=white,bg=red!75!black}
  \setbeamercolor{block body}{use=structure,fg=black,bg=red!20!white}
  \begin{theorem}
    Text
  \end{theorem}
\end{frame}
