如何去除LaTeX模板中\ref和\cite链接的着色效果？

在Overleaf平台使用学校提供的LaTeX模板时，生成的PDF查看器中\ref和\cite链接带有颜色标记，此前编写的LaTeX文档从未出现这种情况，请问是哪些设置导致了这些颜色标记？

以下是文档开头的设置代码：

\usepackage[english]{babel}
\selectlanguage{english}


%-----------------------------------------------------------------
% Activating style packages
%-----------------------------------------------------------------
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{microtype}


%-----------------------------------------------------------------
% Settings for referencing (via Natbib)
%-----------------------------------------------------------------
\usepackage[backend=biber, style=apa]{biblatex}
\addbibresource{ThesisExample.bib}


%-----------------------------------------------------------------
% Graphicx package and hyper referencing
%-----------------------------------------------------------------

\usepackage{graphicx} % Handles import graphics
\usepackage{hyperref} % Hyper referencing
\usepackage{lscape}   % Landscape positioning pages
\usepackage{url}      % Include url codes
\usepackage{booktabs} % Book quality tables

%-----------------------------------------------------------------
% Font selection
%-----------------------------------------------------------------
\usepackage{palatino} % Set palatino font
\usepackage{mathpazo} % Idem, but for math environment

%-----------------------------------------------------------------
% Graphics settings
%-----------------------------------------------------------------
\DeclareGraphicsRule{.jpg}{bmp}{}{}
\graphicspath{{./}}

%-----------------------------------------------------------------
% Removing indentation, include french (non US) spacing
%-----------------------------------------------------------------
%\setlength{\parindent}{0pt}
%
\newcommand{\mySkip}{0pt}
\setlength{\parskip}{\mySkip}

\frenchspacing

%-----------------------------------------------------------------
% Activate tikz and include some specific packages
%-----------------------------------------------------------------
\usepackage{tikz}
\usetikzlibrary{snakes, calc, positioning}


%-----------------------------------------------------------------
% Latex logo (unclear what you need it for)
%-----------------------------------------------------------------
\usepackage{doc}

 
%-----------------------------------------------------------------
% Blank page
%-----------------------------------------------------------------
 
\newcommand*{\blankpage}{%
   \vspace*{\fill}
   \thispagestyle{empty}
   \clearpage
} % end new command
 

%-----------------------------------------------------------------
% Hyper setup
%-----------------------------------------------------------------
 
\hypersetup{
    pdftitle = {My thesis},
    pdfauthor = {My name},
    pdfsubject = {My topic},
    hidelinks
}

• 你已经在\hypersetup里添加了hidelinks来隐藏链接的颜色和边框，但问题出在包的加载顺序：hyperref包需要尽量放在所有其他包的最后加载（除了少数特殊包如cleveref），而你的代码里hyperref是在tikz、doc等包之前加载的，这会导致hidelinks无法正常生效，甚至被后续包的设置覆盖，因此出现了颜色标记。
• 解决方法：把\usepackage{hyperref}移到所有其他包的最后，保持\hypersetup在它之后即可。

调整后的核心代码片段示例：

% 先加载所有其他包...
\usepackage{tikz}
\usetikzlibrary{snakes, calc, positioning}
\usepackage{doc}

% 最后加载hyperref
\usepackage{hyperref} % Hyper referencing

\hypersetup{
    pdftitle = {My thesis},
    pdfauthor = {My name},
    pdfsubject = {My topic},
    hidelinks
}

你也可以直接在加载hyperref时传入hidelinks选项，效果完全相同：

\usepackage[hidelinks]{hyperref}
