Letting us change the color of the String for the Network ID

[LuziferSenpai]

Hey,

for my Colorblind Circuit Network mod, I would love to beable to change the color of the Network ID inside all of the entities that use it.
Why?
Because its hard for colorblind people to read that.
And my mod already changes the colors red to blue and green to yellow.

Greetz,

Luzifer
