# Set color of title-background

I'm trying to give the title (and the title only (with some margin), not the entire page) in the first page of my presentation background color "greyone". This background-box should be page-wide while text is centered. I haven't been able to figure out how to..

I've defined a new beamer template in my preamble by

\documentclass['serif]{beamer}
\usecolortheme{eelke}
% INFORMATION
\title{Presentation Title}
\author{A. Uthor}
% FRONTPAGE
\defbeamertemplate*{title page}{eelke}[1]
{
\centering
\usebeamerfont{title}\inserttitle\par % this should have a background box in color grayone. Text should be white for readability.
\vskip20pt
\usebeamercolor[bg]{titlelike}
\setbeamerfont{author}{size=\fontsize{11}{15}}
\usebeamerfont{author}\insertauthor\par %
\vskip20pt
\setbeamerfont{date}{size=\fontsize{11}{15}}
\usebeamerfont{date}\insertdate\par} \begin{document}\begin{frame}\maketitle\end{frame}\end{document}




Further I have defined a new color in beamercolorthemeeelke.sty file

\definecolor{greyone}{RGB}{77,77,77}
\setbeamercolor{palette quaternary}{fg=white,bg=greyone, wd=\paperwidth}
\setbeamercolor{titlelike}{parent=palette quaternary}


which is called for in the preamble: \usecolortheme{eelke}

Can anyone help me out?

• Please make your code compilable, starting with \documentclass{...} and ending with \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to help you. Help them help you: remove that one hurdle between you and a solution to your problem. – jubobs Nov 19 '13 at 10:39
• I've changed it to a compilable code. – Halbertsma Nov 19 '13 at 11:36

You can use a beamercolorbox but with beamerleftmargin and beamerrightmargin previously added to textwidth.

\documentclass['serif]{beamer}
%\usecolortheme{eelke}

\definecolor{greyone}{RGB}{77,77,77}
\setbeamercolor{palette quaternary}{fg=white,bg=greyone}
\setbeamercolor{titlelike}{parent=palette quaternary}

% INFORMATION
\title{Presentation Title}
\author{A. Uthor}
% FRONTPAGE
\makeatletter
\defbeamertemplate*{title page}{eelke}[1]
{
\@tempdima=\textwidth%
\begin{beamercolorbox}[sep=1em,wd=\the\@tempdima]{titlelike}

\usebeamerfont{title}\inserttitle\par % this should have a background box in color grayone. Text should be white for readability.
\end{beamercolorbox}

\usebeamercolor[bg]{titlelike}
\setbeamerfont{author}{size=\fontsize{11}{15}}
\usebeamerfont{author}\insertauthor\par %
