Beamer：华沙风格书目颜色

Question

在比默， 我在用华沙风格。在参考书目中，我使用\newblock不同类型的条目（作者、标题、期刊等）。我在哪里可以了解颜色关于这些结构的信息（在哪个文件中，在哪一行）？例如，当我在文本中提到作者姓名时，我希望用与在参考书目。

Answer 1

相关信息可参见10.6 添加参考书目手册beamer。您正在寻找的相关颜色/模板/字体是

• bibliography entry author

• bibliography entry title

• bibliography entry location

• bibliography entry note

如果你想查看参考书目的实际定义，你可以查看文件beamerbaselocalstructure.sty。例如，在那里可以找到：

\def\beamer@newblock{%
  \usebeamercolor[fg]{bibliography entry author}%
  \usebeamerfont{bibliography entry author}%
  \usebeamertemplate{bibliography entry author}%
  \def\newblock{%
    \usebeamercolor[fg]{bibliography entry title}%
    \usebeamerfont{bibliography entry title}%
    \usebeamertemplate{bibliography entry title}%
    \def\newblock{%
      \usebeamercolor[fg]{bibliography entry location}%
      \usebeamerfont{bibliography entry location}%
      \usebeamertemplate{bibliography entry location}%
      \def\newblock{%
        \usebeamercolor[fg]{bibliography entry note}%
        \usebeamerfont{bibliography entry note}%
        \usebeamertemplate{bibliography entry note}}}}%
  \leavevmode\setbox\beamer@tempbox=\hbox{}\ht\beamer@tempbox=1.5em\box\beamer@tempbox}

每个主题都可以根据需要重新定义这些颜色/模板/字体。大多数主题使用默认主题的定义。例如，对于所涉及的颜色，在文件中有beamercolorthemedefault.sty：

\setbeamercolor{bibliography entry author}{use=structure,fg=structure.fg}
\setbeamercolor{bibliography entry title}{use=normal text,fg=normal text.fg}
\setbeamercolor{bibliography entry location}{use=structure,fg=structure.fg!65!bg}
\setbeamercolor{bibliography entry note}{use=structure,fg=structure.fg!65!bg}

请注意，为了使用这些颜色，您不需要知道确切的颜色定义（模型等）。如果您想使用这些属性，那么您可以使用\usebeamercolor, \usebeamerfont；一个小例子：

\documentclass{beamer}
\usetheme{Warsaw}

\begin{document}

\begin{frame}
\frametitle{Bibliography colors}
{\usebeamercolor[fg]{bibliography entry author}
\usebeamerfont{bibliography entry author}Author}

{\usebeamercolor[fg]{bibliography entry title}
\usebeamerfont{bibliography entry title}Title}

{\usebeamercolor[fg]{bibliography entry location}
\usebeamerfont{bibliography entry location}Location}

{\usebeamercolor[fg]{bibliography entry note}%
\usebeamerfont{bibliography entry note}Note}
