I don't see an easy way to do this. What makes this even more complex is
that with lines your third dimension (r) is not well defined. For points
you can always assign a color to the point, but a line lives between two
points. What color do you assign to the line?
Of course there are complicated ways to do something like this:
The most straightforward way I can think of at the moment is to create
the paths between the points by hand, then splitting these paths and
then drawing each of these subpaths with colors according to the colors
at your points.
HTH,
