The option is undocumented (at least as far as I have seen). And it
must be used when loading hyperref (when used with \hypersetup as you
have tried, a warning is issued that the option will have no effect).

With the following file:





\section{test section}\label{test}

This a test to see whether the label \ref{test} prints correctly.


You will see that the color shows up on screen, but it is black when
printed (either virtually to another PDF file or physically to a

That is, the reference showed on the screen in the very light color that I chose to heighten the effect and printed in exactly the same way.  So the net effect of ocgcolorlinks appears to be nil.  Incidentally it apparently doesn't appear at all in the hyperlinks documentation.  I am using TeXLive 2014 with Win 7, but that doesn't matter because anything we use will have to work for everybody.
