I'd like to change the color of a footnote, both the text and the mark in a presentation I'm preparing using beamer. The example I give below works in article but not in beamer...any ideas why not?

%\documentclass{article} %works.
\documentclass{beamer}   %does not work.
\usepackage{color}
\renewcommand{\thefootnote}{\color{red}\fnsymbol{footnote}}
\begin{document}
\begin{frame}
Thus we expand every part of the solution, $u, U, V$, and $\lambda$ 
as an asymptotic series\footnote{\color{red}This is 
actually a lie\ldots but don't tell anyone}:
\end{frame}
\end{document}

You could use the beamer class command \setbeamercolor for coloring footnotes and footnote marks, for example:

\setbeamercolor{footnote}{fg=red}
\setbeamercolor{footnote mark}{fg=red}

  • You beat me by a few seconds. I actually found that the second command changed both the footnote mark and text color. Did you find a way to change both independently? – Matthew Leingang Nov 29 '10 at 12:58
  • @Matthew: do you mean the first command? In my opinion it's a good default behavior of the first command to change also the mark color (at least it does it in the footer). Independently - no problem, firstly set text color and afterwards mark color to a different one. – Stefan Kottwitz Nov 29 '10 at 13:38
  • OMM if I do \setbeamercolor{footnote}{fg=green}\setbeamercolor{footnote mark}{fg=red} I get both footnote mark and text in red, not a mark in red and text in green as I would expect. The line separating main text from the footnote is green, though. – Matthew Leingang Nov 29 '10 at 13:51
  • The footnote text is red by default. More testing: \setbeamercolor{footnote}{fg=blue}\setbeamercolor{footnote mark}{fg=green} make the footnote rule blue, the foonote mark green, but the footnote text remains red. – Matthew Leingang Nov 29 '10 at 14:08
  • Now I get it. I was testing on the OP's sample code, which put \color{red} into the footnote argument. Never mind! – Matthew Leingang Nov 29 '10 at 14:20
  • That explains it. I did not see this possibility because I've deleted this \color{red} at first. – Stefan Kottwitz Nov 29 '10 at 14:27

    @Yossi: no problem. I've edited. – Stefan Kottwitz Nov 29 '10 at 15:37
