Further experimentation has shown that it is not impossible to color
\vrule's, thus \blackrule is not specifically needed.
\blackrule is a \vrule which is enclosed in \startcolor/\stopcolor.
Let me first mention that I put the colored rules away with
\setbox\B=\hbox{} and then later call \B up.
Why so complicated?
It is a pity until now I am not able to concoct a
minimal example showing consistently the behaviour.
However I have made the following observations:
define: \definecolor[mycolor][r=myR,g=myG,b=myB]
Have you tried '{\mycolor\vrule <spec>\relax}'?
