標題中部分名稱的投影機顏色設置

這指導解釋如何產生動態標題，其中突出顯示當前部分。

但是如何控制用於突出顯示的顏色呢？ （為了節省空間，我將標題的字體大小設為一個較小的值，因此我想添加一些對比度，以使其更清楚我們在演講的哪個部分）。

如果我正確理解你的問題，這是一個可能的解決方案；我在一般目錄和每個部分開頭生成的目錄中的部分標題周圍添加了彩色邊框：

\documentclass{beamer}
\usepackage{tikz}
\usetheme{Malmoe}

\newcommand\sectioncolor{white}

\newcommand\SectionBox[1]{%
  \tikz\node[rectangle,fill=\sectioncolor,rounded corners] {#1};
}

\AtBeginSection{%
  \setbeamercolor{section in toc}{fg=black,bg=\sectioncolor}
  \begin{frame}<beamer>
  \frametitle{Outline \thesection}
  \tableofcontents[currentsection,subsectionstyle=show/show/shaded]
  \end{frame}
}

\setbeamertemplate{section in toc shaded}[default][7]

\makeatletter
\long\def\beamer@section[#1]#2{%

      \renewcommand\sectioncolor{%
      \ifcase\value{section}\or blue!20\or green!80!black\or red!80!black!50\or yellow!30!black!50\else orange!30!black!50\fi}
    \beamer@ifempty{#2}%
    {\long\def\secname{#1}\long\def\lastsection{#1}}%
    {\global\advance\beamer@tocsectionnumber by 1\relax%
      \long\def\secname{#2}%
      \long\def\lastsection{#1}%
      \addtocontents{toc}{\protect\beamer@sectionintoc{\the\c@section}%
        {\protect\tikz\protect\node[rectangle,fill=\sectioncolor,rounded corners] {#2};}%

由於導覽列中的部分需要修改，而不是像我最初想的那樣在目錄中，因此解決方案要容易得多：所需要做的就是重新定義模板section in head/foot（針對當前部分）和section in head/foot shaded（針對與當前部分不同的部分）當前的一個）。在下面的範例中，我為當前部分使用了彩色框架，但您可以使用您喜歡的任何其他樣式：

\documentclass{beamer}
\usepackage{tikz}
\usetheme{Singapore}

\definecolor{SectionBox}{RGB}{60,160,0}

\setbeamertemplate{section in head/foot}{\hfill\protect\tikz\protect\node[rectangle,fill=SectionBox!90,rounded corners=1pt,inner sep=1pt,] {\textcolor{white}{\insertsectionhead}};}
\setbeamertemplate{section in head/foot shaded}{\textcolor{structure!40}{\hfill\insertsectionhead}}


\begin{document}

\section{Test Section One}
\subsection{Test Subsection One One}
\begin{frame}test section one\end{frame}
\subsection{Test Subsection One Two}
\begin{frame}test section  one\end{frame}

\section{Test Section Two}
\subsection{Test Subsection Two One}
\begin{frame}test section  two\end{frame}
\subsection{Test Subsection Two Two}
\begin{frame}test section  two\end{frame}
\subsection{Test Subsection Two Three}
\begin{frame}test  section  two\end{frame}

\section{Test Section Three}
\subsection{Test Subsection Three One}
\begin{frame}test section  three\end{frame}
\subsection{Test Subsection Three Two}
\begin{frame}test section  three\end{frame}

\end{document}
