改变引文的颜色！

Question

看起来该hyperref包已经加载到您的Thesis.cls类文件（第 128-131 行）中。

使用\hypersetup（在您的手稿中，而不是类文件中）来更改的行为hyperref。例如，如果您想要蓝色引用，请使用：

\hypersetup{citecolor=blue}

看这个答案了解所有可能情况的列表:)

编辑Thesis.cls提供完整详细信息。我只注释了删除包的第 117 行，lstpatch在我的情况下，该包引发了错误（由于缺少该包）：

%\usepackage{lstpatch}

正文如下：

\section{Citation example}

First citation~\cite{latexcompanion}. 

Second where I change the citation color locally using braces:~{\hypersetup{citecolor=red}\cite{latexcompanion}}. 

The colour is set back to its previous value automatically~\cite{latexcompanion}.

\include{ChapterOne}
\include{ChapterTwo}
\include{ChapterThree}
\include{ChapterFour}
\include{ChapterFive}


\cleardoublepage
\addcontentsline{toc}{chapter}{References}
\bibliographystyle{mnras}
%\bibliography{library}
\begin{thebibliography}{9}
\bibitem{latexcompanion} 
Michel Goossens, Frank Mittelbach, and Alexander Samarin. 
\textit{The \LaTeX\ Companion}. 
Addison-Wesley, Reading, Massachusetts, 1993.
 \end{thebibliography}


\appendix
\include{AppendixOne}
\include{AppendixTwo}
\include{AppendixThree}
\printindex{}
\end{document}

注意\hypersetup{citecolor=blue}第 34 行。

其结果如下：
