投影仪海报中定理陈述的彩色文本

Question

我正在使用模板的修改版本这里我听从了给出的建议这里以“内联”模式而不是“块”模式排版定理。

我现在需要修改定理的字体，使其变为浅蓝色，包括标题“定理”（或任何其他名称）和数学。我一直尝试但未成功的代码是这样的

\makeatletter
\setbeamertemplate{theorem begin}
{%
%\inserttheoremheadfont %\bfseries
{\bfseries \inserttheoremname} %\inserttheoremnumber
\ifx\inserttheoremaddition\@empty\else\ (\inserttheoremaddition)\fi%
%\inserttheorempunctuation
\hspace{.01em}
\normalfont
  \setbeamercolor{block body}{fg=black,bg=blue!40}
 }
 \setbeamertemplate{theorem end}{%
  % empty
  }
  \makeatother

我也尝试过\AtBeginEnvironment{theorem}{% \setbeamercolor{block body}{fg=black,bg=blue!40} }按照建议这里但我收到“未定义的控制序列：\AtBeginEnvironment”错误。

有什么想法吗？提前致谢！

以下是一种方法：

代码：

\documentclass{beamer}
\setbeamercolor*{thcolor}{fg=blue!60}

\makeatletter
\setbeamertemplate{theorem begin}
  {\usebeamercolor[fg]{thcolor}% for the heading
  {\bfseries\inserttheoremname~}%
  \ifx\inserttheoremaddition\@empty\else(\inserttheoremaddition)\ \fi%
  \hspace{.01em}\normalfont\usebeamercolor[fg]{thcolor}% for the body
  }
\setbeamertemplate{theorem end}{}
\makeatother

\begin{document}

\begin{frame}
  \begin{theorem}
  A test theorem.
  \end{theorem}
  \begin{corollary}
  A test corollary.
  \end{corollary}
  \begin{theorem}[Zorn's Lemma]
  A test theorem with annotation.
  \end{theorem}
\end{frame}

\end{document}
