Blue is the correct colour for the polarised DC postive from track power to supply accessories like lights.

Others don't think so.

Two of the Phoenix 10 pin P5T output cables are blue. BOTH are connected to the pcb ground.
Perhaps you would care to lend your weight to approach Phoenix to get it right?

As a matter of interest, and a serious question. Can you tell me what the correct colour wiring is used for the DCC pcb common ground?

Is it Black with a white trace?
