\begin{HBox}{Fancy colors for card symbols\hfill File: \FileName}
Due to the definition of the card symbols, a simple redefinition like:\\
\verb|\let\MyClub\Cl|\\
\verb|\renewcommand{\Cl}{%|\\
\verb|\textcolor{green}{\MyClub}}|\\
will \textbf{not} change the color of the symbol.
For details refer to the \OneDown manual, section 6.2.1 \emph{Suit Symbols}.

Instead put in your preamble e.g. this code to get \textcolor{green}{green}
clubs, \textcolor{orange}{orange} diamonds, \textcolor{red}{red} hearts and
\textcolor{blue}{blue} spades.
\\[\baselineskip]
\verb|\makeatletter|\\
\verb|\renewrobustcmd\Cl{%|\\
\verb|\textcolor{green}%|\\
\verb|{\,[0.3]\ensuremath{%|\\
\verb|\ODw@clubsuit}}\xspace}%|\\[2mm]
\verb|\renewrobustcmd\Di{%|\\
\verb|\textcolor{orange}%|\\
\verb|{\,[0.3]\ensuremath{%|\\
\verb|\ODw@vardiamond}}\xspace}%|\\[2mm]
\verb|\renewrobustcmd\He{%|\\
\verb|\textcolor{red}%|\\
\verb|{\,[0.3]\ensuremath{%|\\
\verb|\ODw@varheart}}\xspace}%|\\[2mm]
\verb|\renewrobustcmd\Sp{%|\\
\verb|\textcolor{blue}%|\\
\verb|{\,[0.3]\ensuremath{%|\\
\verb|\ODw@spadesuit}}\xspace}%|\\
\verb|\makeatother|
\\[\baselineskip]
Now you will get yor own fancy colors:

1\Cl, 2\Di, 3\He, 4\Sp\\
