colors appropriately:
\documentclass{beamer}
\AtBeginSection[]
{
\setbeamercolor{section in toc}{fg=alerted text.fg}
\setbeamercolor{section in toc shaded}{fg=structure}
\begin{frame}<beamer>
\frametitle{Outline}
\tableofcontents[currentsection]
\end{frame}
}
\begin{document}
\section{Test section one}
\begin{frame} test \end{frame}
\section{Test section two}
\begin{frame} test \end{frame}
\section{Test section three}
\begin{frame} test \end{frame}
\section{Test section four}
\begin{frame} test \end{frame}
\end{document}

A complete example:
\documentclass{beamer}
\AtBeginSection[]
{
\setbeamercolor{section in toc}{fg=alerted text.fg}
\setbeamercolor{section in toc shaded}{bg=structure!20,fg=structure}
\setbeamertemplate{section in toc shaded}[default][100]
\begin{frame}<beamer>
\frametitle{Outline}
\tableofcontents[currentsection]
\end{frame}
}
\begin{document}
\section{Test section one}
\begin{frame} test \end{frame}
\section{Test section two}
\begin{frame} test \end{frame}
\section{Test section three}
\begin{frame} test \end{frame}
\section{Test section four}
