User set color for connecting wires or wireless...

So I built a massive machine and have a rat’s nest of wires. I know I can route them with routing points, but a way to color code them would really help.

Another way to do it might be if I could create wireless connections, with a small device that will allow me to connect one item to it, then somewhere else in my machine another small device that allows me to output one connection. They two will be connected invisibly and would be color coded or have a user generated identifier. Maybe you could connect multiple outputs from the same input. See attached image.
