Changing the color of \ref within the same document

Question

Is there a way to reference things with \ref using a different color than with what \hypersetup assigns it? That is, I would like to reference a theorem with blue text in general, but at some point I'd like to reference it with red text. I've tried using \textcolor but that doesn't seem to override it.

You can switch colours mid-document using \hypersetup:

\documentclass{article}

\usepackage{hyperref,xcolor}

\hypersetup{
  colorlinks % Defaults to red
}

\begin{document}

\section{A section}\label{sec:section}

See Section~\ref{sec:section}.

\hypersetup{linkcolor=green}

See Section~\ref{sec:section}.

\hypersetup{linkcolor=red}

See Section~\ref{sec:section}.

\end{document}
