It looks like that the verbatim environment with the coloring, but I'm not sure.
How can one can use color for verbatim like environment as is shown?
Using line by line method would be a solution, but I expect a better way to go.
{\color{red}\begin{verbatim}
line 1
line 2
\end{verbatim} }
\color{blue}{\begin{verbatim}
line 3
line 4
\end{verbatim}}
It seems to me that what you really want, is to customize the look of the captions. This is most easily done using the caption package. For instructions how to use this package, see the manual (PDF). You would probably need to create your own custom caption format, as described in chapter 4 in the manual.
Edit: Tested with MikTex:
\documentclass{report}
\usepackage{color}
\usepackage{xcolor}
\usepackage{listings}
\usepackage{caption}
\DeclareCaptionFont{white}{\color{white}}
\DeclareCaptionFormat{listing}{\colorbox{gray}{\parbox{\textwidth}{#1#2#3}}}
\captionsetup[lstlisting]{format=listing,labelfont=white,textfont=white}
% This concludes the preamble
\begin{document}
\begin{lstlisting}[label=some-code,caption=Some Code]
public void here() {
goes().the().code()
}
\end{lstlisting}
\end{document}
Result:
Environment definition:
\newenvironment{VerbExample}
{\example\semiverbatim}
{\endsemiverbatim\endexample}
Frame definition:
\begin{frame}[fragile]
\frametitle{Title}
\begin{VerbExample}
test test test $t$ $\\omega$
test test
\end{VerbExample}
\end{frame}
Verbatim cannot go inside \newcommand. Semiverbatim is defined by Beamer and works well with it. The three characters \ { } must be escaped as \\ \{ \}.
