# How to change Footnote color in only one slide?

For some reason I want to change the color of my citations in my slides. I am using the code posted in here

Why \footcite not working in beamer?

as a MWE.

\documentclass{beamer}
\usepackage[style=verbose]{biblatex}

\usepackage{filecontents}% to embed the file myreferences.bib in your .tex file
\begin{filecontents*}{myreferences.bib}
@online{foo12,
year = {2012},
title = {footnote-reference-using-european-system},
url = {https://tex.stackexchange.com/questions/69716/footnote-reference-using-european-system},
}
\end{filecontents*}

% File is created and written to disk by the above package

\begin{document}

\begin{frame}
footcite is in default color blue here.\footcite{foo12}
\end{frame}

\begin{frame}
How to make footcite red color here.\footcite{foo12}
\end{frame}

\begin{frame}
\printbibliography
\end{frame}

\end{document}


How can I do this? I tried using \color{red} to make citation appear in red but it didnt work.

To change the colour locally for one frame, put the commands inside e.g. {} in order to keep the changes within this group.
