Color - How to make a few letters in an equation have color

I have an equation: y = 2x + 3. How would I make the 2x red in equation mode in beamer?

For beamer, perhaps coloured math in beamer is a better duplicate. — Peter Grill, Feb 09 '12 at 22:36
@PeterGrill: But would the solution suggested in that answer work for just parts of an equation? It seems like it just explains how to switch the colour for maths stuff in general. — Jake, Feb 09 '12 at 22:53
@Jake: Obviously I have not had enough coffee today... You are correct. So the first one is probably a better duplicate. — Peter Grill, Feb 09 '12 at 23:00

\documentclass{beamer}
\usepackage{graphicx}
\author{Kaare Mikkelsen}
\begin{document}
\frame{
\frametitle{Colors}
\begin{equation}
\textcolor{red}{e}=\textcolor{blue}{m}\textcolor{green}{c}^2
\end{equation}
}
\end{document}

if you look into the documentation of the graphicx package (http://ctan.org/pkg/graphicx), you can also define your own colors.
