使用 CambridgeUS 更改投影机的颜色和标题

Question

要更改框架标题以及标题和副标题的颜色，您需要重新定义beamer颜色frametitle和title：

\setbeamercolor{frametitle}{<color>}
\setbeamercolor{title}{<color>}

要更改标题的位置，您需要重新定义headline外部主题中定义的模板infolines（由内部使用CambridgeUS）。这是原始定义：

\defbeamertemplate*{headline}{infolines theme}
{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.5\paperwidth,ht=2.65ex,dp=1.5ex,right]{section in head/foot}%
    \usebeamerfont{section in head/foot}\insertsectionhead\hspace*{2ex}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.5\paperwidth,ht=2.65ex,dp=1.5ex,left]{subsection in head/foot}%
    \usebeamerfont{subsection in head/foot}\hspace*{2ex}\insertsubsectionhead
  \end{beamercolorbox}}%
  \vskip0pt%
}

如您所见，第一个框的对齐方式beamercolorbox是right，第二个框的对齐方式是left：您可以根据需要更改这些。

在下面的例子中，我使用了青色作为标题（不是最好的选择），并且我center在两个框中都使用了headline：

\documentclass{beamer}

\usetheme{CambridgeUS}
