beamer：遮蔽块环境

Question

我希望block环境用蓝色阴影表示，因为现在几乎看不出来。我使用的 LaTeX 代码是

\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}

Answer 1

考虑rose除了Goettingen主题之外还使用颜色主题——这样，block环境将呈现与侧边栏颜色很好地搭配的浅蓝色。

\documentclass[10pt]{beamer}
\mode<beamer>{%
\usetheme[hideothersubsections,right,width=22mm]{Goettingen}
\usecolortheme{rose}
}

\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}
