How to change link color in NS2?

Question

So here's my topology. In my tcl script i added a line to make the link between node 2 and 3 to go down at some point. As you can see (link below), NAM shows it in RED as soon as it goes down. What i want to do is to change that default color (red) to another color of my choice. Is it possible to that ? If yes, how?
