如何获得浅蓝色的超链接颜色？

Question

考虑一下这篇论文：https://www.sciencedirect.com/science/article/pii/S0960077922011948

我们如何实现链接的浅蓝色？

从这个问题的答案来看：将超链接扩展至图 a、b、c：

\documentclass[10pt,a4paper]{book}
    \usepackage[T1]{fontenc}
    \usepackage{lmodern}
    \usepackage{todonotes}
    \usepackage[colorlinks,linkcolor=black,anchorcolor=black,citecolor=black,filecolor=black,urlcolor=blue]{hyperref}
    
    \newcommand*{\figref}[2][]{%
      \hyperref[{fig:#2}]{%
        Figure~\ref*{fig:#2}%
        \ifx\\#1\\%
        \else
          \,#1%
        \fi
      }%
    }
    
\begin{document}
\hypersetup{linkcolor=blue}
\chapter{one}
    
    \begin{figure}[t]
       \missingfigure[figwidth=6cm]{- << Ciel, mon mari >> dit-elle !}
    \caption{a: Missing figure, and b: still missing figure.}
    \label{fig:missing Figure}
    \end{figure}
    
    The figure \figref{missing Figure} contains two subfigures.
    Something in \figref[a]{missing Figure} and some other thing in
    Figure \figref[b]{missing Figure}.
    
\end{document}

所以，显然你自己解决了你的问题，把你的代码和最后的评论放在一起......可以通过使用一些粉红色来轻松验证：

\hypersetup{linkcolor=[rgb]{1,0.5,0.73}}% ;-)

\documentclass[10pt,a4paper]{book}
    \usepackage[T1]{fontenc}
    \usepackage{lmodern}
    \usepackage{todonotes}
    \usepackage[colorlinks,linkcolor=black,anchorcolor=black,
    citecolor=black,filecolor=black,urlcolor=blue]{hyperref}
    
    \newcommand*{\figref}[2][]{%
      \hyperref[{fig:#2}]{%
        Figure~\ref*{fig:#2}%
        \ifx\\#1\\%
        \else
          \,#1%
        \fi
      }%
    }
    
\begin{document}
%\hypersetup{linkcolor=blue}
\hypersetup{linkcolor=[rgb]{0,0.5,0.73}}% <<<<<<<<<<<<<<
\chapter{one}
    
    \begin{figure}[t]
       \missingfigure[figwidth=6cm]{- << Ciel, mon mari >> dit-elle !}
    \caption{a: Missing figure, and b: still missing figure.}
    \label{fig:missing Figure}
    \end{figure}
    
    The figure \figref{missing Figure} contains two subfigures.
    Something in \figref[a]{missing Figure} and some other thing in
    Figure \figref[b]{missing Figure}.
    
\end{document}
