FIRST and the inspectors, are pretty set on the rules.
A couple of years ago, we wired our dc motor power with black wire with yellow tracers, and the inspectors at Waterford made us cover the yellow tracer with black tape during inspection.
I work in industrial controls, we are panel build shop, and I have access to a bunch of wire, that is donated to the team, so I like to use tracer colors to segregate function and amperage loads, but after that, we stick with red and black.
Don't poke the bear.
