# beamer: shading the block environment

I want the block environment to be shaded in blue, because now it is hardly noticeable. The LaTeX code I'm using is

\documentclass[10pt]{beamer}
\mode<beamer>{%
\usetheme[hideothersubsections,
right,width=22mm]{Goettingen}
}
\title{Math}
\author[Mister X]{X}
\institute{University}
\titlegraphic{\includegraphics[width=20mm]{USTL}}
\date{January 15, 2012}

\begin{document}
\begin{frame}<handout:0>
\titlepage
\end{frame}
\begin{frame}
The following proposition is easy to prove.
\begin{block}{Proposition}
some statement
\end{block}

\end{frame}
\end{document}


Consider to use the rose color theme in addition to the Goettingen theme -- this way, the block environment will feature light blue colors which go together well with the sidebar colors.

\usetheme[hideothersubsections,right,width=22mm]{Goettingen}
\usecolortheme{rose}
