[Tex/LaTex] Frame numbering in Warsaw theme

beamerheader-footer

This is a follow-up question to slide numbering in Beamer class (Warsaw theme)

In fact, I was trying to put frame numbering in my presentation using Warsaw theme. All I wanted is to put the numbering on bottom right corner. Therefore, I modified the option given by @CarstenThiel in the above link as

\defbeamertemplate*{footline}{shadow theme}{%
\leavevmode%
\hbox{\begin{beamercolorbox}[wd=.5\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.3cm plus1fil,rightskip=.3cm]{author in head/foot}%
    \usebeamerfont{author in head/foot}\hfill\insertshortauthor
\end{beamercolorbox}%

\begin{beamercolorbox}[wd=.5\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.3cm,rightskip=.3cm plus1fil]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle\hfill%
\insertframenumber\,/\,\inserttotalframenumber
\end{beamercolorbox}}%
\vskip0pt%
}

Similarly, @MikeR's answer at Beamer: Hide Backup Slides from Navigation Panel works the same:

\expandafter\def\expandafter\insertshorttitle\expandafter{%
    \insertshorttitle\hfill\insertframenumber\,/\,\inserttotalframenumber}

My question here is that, is it possible for me to have a different color in the frame numbering area as shown below?enter image description here

Best Answer

You can add another beamercolorbox to the footline template and add the information about the frame numbers there, using the desired color; a little example:

\documentclass{beamer}
\usetheme{Warsaw}

\setbeamercolor{mycolor}{fg=red,bg=olive}

\defbeamertemplate*{footline}{shadow theme}{%
\leavevmode%
\hbox{\begin{beamercolorbox}[wd=.5\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.3cm plus1fil,rightskip=.3cm]{author in head/foot}%
    \usebeamerfont{author in head/foot}\hfill\insertshortauthor
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.4\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.3cm,rightskip=.3cm plus1fil]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle\hfill%
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.1\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.3cm,rightskip=.3cm plus1fil]{mycolor}%
\hfill\insertframenumber\,/\,\inserttotalframenumber
\end{beamercolorbox}}%
\vskip0pt%
}
