这个问题显然与这个，作者并未继续提供可行的示例。
我想将\citeauthor链接的颜色设为黑色，将 的颜色\cite设为蓝色。在下面的例子中，作者和引用编号均为蓝色，而 显然没有关键字citeauthorcolor。hyperref我该如何制作不同的颜色？
主文本
\documentclass[12pt]{article}
\usepackage[colorlinks=true, citecolor=blue]{hyperref}
\usepackage[numbers]{natbib}
\begin{document}
The work by \citeauthor{myref} was a fancy read~\cite{myref}.
\bibliographystyle{plainnat}
\bibliography{main}
\end{document}
主目录
@article{myref,
title = {Fancy title},
journal = {Journal of Fancy Publications},
author = {Jane Dee and John Doe},
year = {2017},
pages = {293--311},
}
编译：pdflatex main; bibtex main; pdflatex main; pdflatex main;
答案1
这是一个“黑客”行为：
\documentclass[12pt]{article}
\usepackage[colorlinks=true, citecolor=blue]{hyperref}
\usepackage[numbers]{natbib}
\usepackage{filecontents}
\let\oldciteauthor=\citeauthor
\def\citeauthor#1{\hypersetup{citecolor=blue}\oldciteauthor{#1}}
\let\oldcite=\cite
\def\cite#1{\hypersetup{citecolor=red}\oldcite{#1}}
\begin{filecontents}{main.bib}
@article{myref,
title = {Fancy title},
journal = {Journal of Fancy Publications},
author = {Jane Dee and John Doe},
year = {2017},
pages = {293--311},
}
\end{filecontents}
\begin{document}
The work by \citeauthor{myref} was a fancy read~\cite{myref}.
\bibliographystyle{plainnat}
\bibliography{main}
\end{document}
输出：
