Are you suggesting this just for closed curves? Or are you talking about
the line color itself? Either way, adding a color option doesn't seem
that bad. Additonally, there is no need for a new method. We can just
change the declaration from
void GR_UnixGraphics::polyLine(UT_Point * pts, UT_uint32 nPoints);
to
void GR_UnixGraphics::polyLine(UT_Point * pts, UT_uint32 nPoints,
UT_ColorType color=black /*or whatever the default is*/);
I'm pretty sure that this will do everything we want. At least that's
what my Stroustrup book tells me. But others more versed in C++ may
correct me.

This is an excellent idea, in my humble opinion. Especially if you're
planning to provide the code. :-)
