Document Classes ⇒ beamer | Change Appearance of Citations

[Markus Schwarz]

Hello all,

I have this simple question, but I haven't found an answer to it yet:
Using beamer, how do I change the way citations appear on the slides?

In particular, I want the reference cited with the author name in red text.

So far, I am using

Code: Select all

\documentclass[t]{beamer}
\beamertemplatenavigationsymbolsempty

\begin{frame}[allowframebreaks]{References}
\begin{thebibliography}{99}
  \bibitem[Herbst,Hofmann\,'04]{Herbst04}
  U.~Herbst, R.~Hofmann,
  \newblock Asymptotic freedom and compositeness
  \newblock [hep-th/0411214].
\end{frame}

When I use \cite{Herbst04} it is cited as "[Herbst,Hofmann\,'04]", but in normal text color. How do I change this to red? Using

Code: Select all

\bibitem[{\usebeamercolor[fg]{alerted text} Herbst,Hofmann 04}]{Herbst04}

produces a ton of error messages. I know I can change the color of the author name in the bibliography with

Code: Select all

\setbeamercolor{bibliography entry author}{fg=red}

at the top of the document. Is there a similar command for the cited text?

Thanks for your help!

Hi Markus,

welcome to the board!

Since beamer uses hyperref for generating hyperlinks for citations, you could use hyperref features:

Code: Select all

\hypersetup{colorlinks=true,citecolor=red}

Thanks Stefan for your help and the warm welcome!

While your command did indeed cause all citations to appear red, it does so also for the ToC entries and referred equations. It appears that all are treated as links, and hence inherit the link color red. This could also be caused by a label command (beamer user guide p. 105). I didn't find any obvious way around it in either beamer's or hyperref's documentation.

Is there away to tell beamer that it should not treat sections and equations as links?
