In beamer I would like to make title pages for different presentations with this style:
I looked at https://tex.stackexchange.com/a/116112/36831 but that seems much more complicated than I was hoping for.
I didn't really know where to start but here is some LaTeX nonetheless.
\documentclass{beamer}
\usetheme{default}
\beamertemplatenavigationsymbolsempty
\setbeamertemplate{frametitle}[default][center]
\newcommand{\Var}[1]{\ensuremath{\textcolor{varcolor}{#1}}}
\definecolor{varcolor}{RGB}{15,122,183}
\title{Calculus recap.}
%\Var{\rule{\linewidth}{2pt}}
\author{Author Name}
\date{}
\begin{document}
\begin{frame}[plain]
\maketitle
\end{frame}
\end{document}
