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.
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}:

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

\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

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