At Championships a couple years ago, we used copper wiring with translucent insulation that looked more red-orange than red for the +12V wires. It was the same gauge as required, but more flexible than the KOP red wire (which is why we used it). The inspector did yell at us for that, but we weren't required to fix it.

Regardless, you probably should get the paint off your wiring so you have a better chance to pass inspection.
