This question is about having colored links on screen while printing them black. The solution is
\documentclass{article}
\usepackage[ocgcolorlinks]{hyperref}
\begin{document}
\href{https://tex.stackexchange.com/}{TeX Stackexchange}
\end{document}
I would like to have the same functionality in ConTeXt. The only commands touching link colors that I know of are:
\setupcolors[state=start|stop]
\setupinteraction[state=start|stop,color=...]
/edit: The question ConTeXt: Replace PDF Content During Printing provides the building blocks for a solution. Now we only need to find the code that renders links and replace it with \viewerlayer[view]{\color[#gotocolor]{#text}}\llap{\viewerlayer[print]{#text}}
