Changing color of default enumeration

Question

To my surprise, I've had trouble finding red themes, and used the beamer theme matrix to find CambridgeUS. I've changed the itemized bullets to match, but I can't seem to make the enumerations red. I tried \setbeamertemplate{items}[red] from the beamer manual, and I tried \setbeamertemplate{enumerate items}[default, red] which also didn't work. It looks like it can be done in each enumerate environment like this related question, but is there a way for me to do it once, in the preamble, without defining a custom command? I thought this sort of thing would be common. At the moment my preamble is

\usetheme{CambridgeUS}
\setbeamercolor{item projected}{bg=red}
\setbeamertemplate{enumerate items}[default]
\setbeamertemplate{navigation symbols}{}
\setbeamercovered{transparent}

Alternatively, if there is another template for enumerate items that uses the default markers and is red, that would work too.

EDIT:

I'm able to change the color of the top level number with \setbeamercolor{enumerate item}{fg=red}, but they don't all inherit as I would expect when I try \setbeamercolor{enumerate items}{fg=red}.

EDIT AGAIN:

It looks like using \documentclass[red]{beamer} turns them red (not a great shade or red, but reddish nonetheless). I read somewhere that doing this is obsolete, so please let me know if there is something more current that I should be using.

You can use local structure to cause the colour inheritance:

\documentclass{beamer}
\usetheme{CambridgeUS}
\setbeamercolor{item projected}{bg=darkred}
\setbeamertemplate{enumerate items}[default]
\setbeamertemplate{navigation symbols}{}
\setbeamercovered{transparent}
\setbeamercolor{block title}{fg=darkred}
\setbeamercolor{local structure}{fg=darkred}

\begin{document}

\begin{frame}
\begin{block}{A block}
\begin{enumerate}
  \item First item.
  \begin{itemize}
    \item First subitem.
    \begin{enumerate}
      \item First subsubitem.
    \end{enumerate}
  \end{itemize}
\end{enumerate}
\end{block}
\end{frame}

\end{document}

i presume your \setbeamercolor{block title}{} line just determines the color of the block title...but what is that exactly? another level of nesting, but with no marker, like a description environment? – aeroNotAuto Mar 06 '12 at 01:35
@asia1281 Yes, more or less. They give some internal structure to a slide. I use them quite a bit in my own slides. How useful they are obviously depends a lot on the content of your presentations. You can think of it as a title for each itemized list. – Alan Munn Mar 06 '12 at 02:47

Change the enumerate subitem and enumerate subsubitem colors also:

\documentclass{beamer}
\usetheme{CambridgeUS}
\setbeamercolor{item projected}{bg=red}
\setbeamertemplate{enumerate items}[default]
\setbeamertemplate{navigation symbols}{}
\setbeamercovered{transparent}

\setbeamercolor*{enumerate item}{fg=red}
\setbeamercolor*{enumerate subitem}{fg=red}
\setbeamercolor*{enumerate subsubitem}{fg=red}

\begin{document}

\begin{frame}
\begin{enumerate}
  \item First item.
  \begin{enumerate}
    \item First subitem.
    \begin{enumerate}
      \item First subsubitem.
    \end{enumerate}
  \end{enumerate}
\end{enumerate}
\end{frame}

\end{document}

If you want to use the same color as the one used in CambridgeUS, you can use darkred (defined by the theme) instead of red.

well yes, I know I can do that, but is there no way to do this so that they inherit/are all changed? that can't be the modern replacement for \documentclass[red]{beamer} can it? — aeroNotAuto, Mar 05 '12 at 23:15
