captionsetup url color select

Question

I've changed my caption font color to gray as seen in the screenshot below. My problem is that references is black (which I've chosen in the hypersetup), how do I change this to be gray as the rest of the caption text, while in all other places than the caption the links are black?

I've tried with linkcolor and urlcolor, but it seems like the caption package does not support these options.

Here is my preamble:

\documentclass[11pt, twoside]{report}

\usepackage{hyperref} % clickable references
\hypersetup{
    colorlinks,
    citecolor=black,
    filecolor=black,
    linkcolor=black,
    urlcolor=black
}


% ------- Images ------- %
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}
\DeclareCaptionFont{gray}{\color{gray}}
\captionsetup{
    textfont={footnotesize,sc,gray},
    font={footnotesize,sc,gray},
    %linkcolor={footnotesize,sc,gray},
}



% ------- Colors ------- %
\usepackage{color}
\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{mauve}{rgb}{0.58,0,0.82}

And the code for the table and equation is here:

\begin{equation}
1+K_1K_2\frac{(s+2)^2}{(s+10)(s+100)(s^2+3.535s+6.25)}=0
\label{eq:part_b_characteristic_eq}
\end{equation}


\begin{table}[h!]
\begin{center}
\begin{tabular}{c|l}
$s_n$ & pole\\\hline
$s_1$ & $-100 + 0i$\\
$s_2$ & $-10 + 0i$\\
$s_3$ & $-1.77 + 1.77i$\\
$s_4$ & $-1.77 - 1.77i$\\
\end{tabular}
\end{center}
\caption{Pole values of the system from equation \eqref{eq:part_b_characteristic_eq}}
\label{tab:poles_from_characteristic_eq_partb}
\end{table}

Just add the specification when you define the font for the caption; note that you should load hyperref last.

\documentclass[11pt, twoside]{report}

\usepackage{amsmath} % it was missing


% ------- Images ------- %
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}

% ------- Colors ------- %
\usepackage{color}
\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{mauve}{rgb}{0.58,0,0.82}

% hyperref

\usepackage{hyperref} % clickable references
\hypersetup{
    colorlinks,
    citecolor=black,
    filecolor=black,
    linkcolor=black,
    urlcolor=black
}

% customizations

\DeclareCaptionFont{gray}{\color{gray}\hypersetup{linkcolor=gray}}
\captionsetup{
    textfont={footnotesize,sc,gray},
    font={footnotesize,sc,gray},
}

\begin{document}

\begin{equation}
1+K_1K_2\frac{(s+2)^2}{(s+10)(s+100)(s^2+3.535s+6.25)}=0
\label{eq:part_b_characteristic_eq}
\end{equation}


\begin{table}[h!]
\begin{center}
\begin{tabular}{c|l}
$s_n$ & pole\\\hline
$s_1$ & $-100 + 0i$\\
$s_2$ & $-10 + 0i$\\
$s_3$ & $-1.77 + 1.77i$\\
$s_4$ & $-1.77 - 1.77i$\\
\end{tabular}

I have prepared two new commands \mref and \mpageref which call for \hyperref (Approach 1) or \hypersetup{linkcolor=...} (Approach 2). Please try it if it fits your needs.

%! *latex mal-url-color.tex
\documentclass[11pt, twoside]{report}
\pagestyle{empty}
\usepackage{amsmath}
\usepackage{hyperref} % clickable references
\hypersetup{
    colorlinks,
    citecolor=black,
    filecolor=black,
    linkcolor=gray, % red
    urlcolor=black,
   }
% ------- Images ------- %
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}
\DeclareCaptionFont{gray}{\color{gray}}
\captionsetup{

    font={footnotesize,sc,gray},
    %linkcolor={footnotesize,sc,gray},
    }
