netlogo change color of a link line

Question

The color of a link line seems to be gray how could I change it? (global?) I searched already at the netlogo dict http://ccl.northwestern.edu/netlogo/docs/dictionary.html but didn't found anything about it.

Answer 1

color is a built-in variable of links just as it is the case for turtles, see here.

So this will change the color for all links:

ask links [set color red]
