Beamer metropolis theme: change color of section page

Question

I would like to know a way to change the background color of the section page in the beamer metropolis theme.

I tried something like this:

\setbeamercolor{sectionpage}{fg=blue,bg=blue}

but it didn't work. Any ideas?

cheers,

Answer 1

It is possible to do much damage to the aesthetic styles by changing colours on each frame so you need to avoid glaring contrasts like whot I have done.

I will simply point you a snippet producing the above frames generated by adding after the default title page

\setbeamercolor{background canvas}{bg=cyan!50!white}
\begin{frame}{Outline}
  \tableofcontents
\end{frame}
\setbeamercolor{background canvas}{bg=yellow!50!white}
\setbeamercolor{section title}{fg=white,bg=red!50!black}
\section{Introduction} 

Answer 2

I wanted to make the section pages look like standout frame style in metropolis theme. You can do this by including the following in the preamble:

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

Hope this helps.

Building on the answer by tachyon, I added the following to my preamble

\AtBeginSection{
  {
    \setbeamercolor{section title}{fg=white} % font color 
    \frame[standout]{\sectionpage} % the "standout" keyword makes the background dark
  }
}
