I know how to change the colour of a section name using for example
\section{\color{Red} Foobar}
but that still leaves the section number in black. Is there any way to change the colour of the numbers of the sections, subsections, etc?

You change section numbering by redefining the commands used to generate each section number. For example, the default article class uses something like
\renewcommand\thesection{\arabic{section}}
\renewcommand\thesubsection{\thesection.\arabic{subsection}}
with similar commands like \thesubsubsection and so on -- of course, there's also \thechapter (in the book and report class) and \thepart. Commands to typeset numbers include:
\arabic(1, 2, 3, ...)\alph(a, b, c, ...)\Alph(A, B, C, ...)\roman(i, ii, iii, ...)\Roman(I, II, III, ...)\fnsymbol(∗, †, ‡, §, ¶, ...)
\documentclass[12pt]{article}
\usepackage{xcolor}
\usepackage{listings}
\lstset{literate=%
{0}{{{\color{red}0}}}1
{1}{{{\color{red}1}}}1
{2}{{{\color{red}2}}}1
{3}{{{\color{red}3}}}1
{4}{{{\color{red}4}}}1
{5}{{{\color{red}5}}}1
{6}{{{\color{red}6}}}1
{7}{{{\color{red}7}}}1
{8}{{{\color{red}8}}}1
{9}{{{\color{red}9}}}1
}
\begin{document}
\begin{lstlisting}
This is a test
123 + 456 = 789
\end{lstlisting}
\end{document}

I'm sure there is some package that does this, but the simplest way is to redefine the
\thesectioncommand:or if you also want the chapter number:
Similar commands work for
\thechapter,\thesubsection, etc.EDIT: A maybe unintended side effect of this is that it also color every reference to the section. To just change it in the section header you can use
In any case you might want to have a look at section 2.2 of the LaTeX Companion and the
titlesecpackage.
