Does Fritzing 1.0.6, 1.0.5 , i do mean 2025 releases, allow for color change in pcb traces?
I would like to identify positives, negatives and other signals. This app got far better than what used to be some thing ago, yet, i do believe a feature like this would be of extreme help when trying to develop complex circuits.
I don’t think so. Edit→preferences for pcb view only has curvy wires and legs not colors. Changing thee color I expect would affect gerber processing (which happens after pcb view rendering) and thus is likely to be difficult to implement.

If you press on a connector, it will highlight the subnet.
While @KjellM ‘s suggestion works an even better option on complex boards is to route schematic first. As long as schematic is correct and routed the connections in pcb will appears as rats nest lines in pcb. Click on a line and drag it and it will create a trace going to the correct pin. Drag the trace to what ever configuration you need. It is extremely easy to make mistakes while routing breadboard and pcb, starting with schematic usually provides better results.
