Is it possible to use the dark theme only on the title and section frames?

[joaocandre]

How would I achieve this? I've tried several combinations of keys for both metroset and setbeamercolor but I'm not getting anywhere. Is it possible?

There you go.

\documentclass{beamer}
\usetheme{metropolis}

\AtBeginSection{
  {
    \metroset{background=dark}
    \frame[plain,c,noframenumbering]{\sectionpage}
  }
}


\title{Dark theme on title and section frames only}
\date{\today}
\author{Benjamin Weiss}
\institute{Centre for Modern Beamer Themes}

\begin{document}

{
\metroset{background=dark}
\maketitle
}

\section{First Section}

\begin{frame}{First Frame}
Hello, world!
\end{frame}

\section{Second Section}

\begin{frame}{Second Frame}
Hello, world!
\end{frame}

\end{document}

Thanks! That did it. I guess setting the background at the beggining of each section would also work?

Yes, but you would have to group every \section command, like I did with the title page.
