Thank you so much for this mod. My colorblind eyes needed this SO badly. The ability to configure the color choices is excellent.
Suggestion RE: the brightness randomization: rather than randomization, for each network color, divide the brightness space evenly according to how many IDs need to be drawn and assign them in order. That way you maximize the contrast as much as possible.
Example for red and green:
