Summary

Green wires should be made from copper cable + electronic circuits, red wires from copper cable + advanced circuits and blue wires added to be made from copper cable + processing units.

Explanation

This would add an element of expanding tech base and complexity to the use of control wires. Green wires would be relatively cheap and simple to make, giving you one set of instructions for logistic equipment. Red wires would be a little more expensive and complex to make and give you a second set of instructions for logistic equipment, hence the need for a more complicated circuit type. Blue wires would be very expensive and complex to make, and give you a third set of instructions for logistic equipment, thus requiring a much more complicated type of circuit to make. The choice of wire colour is simply associated with the colour of the circuit used to make it, just to make it easier to remember.

Wires are used very rarely even now; making them more expensive just does not make any sense. Most of the cases you just use roboports network and not wires.

In my opinion green/red wire should cost nothing. Instead they should be part of the poles. They already include normal cables, they could also include red/green cables. Much less hassle.

Making them free also seems a god idea for me.
