Aircraft wire is generally all one color for the most part although aside from mostly white, it is available in black and a few other colors by special order. Manufacturers apply a lazer inscribed code every 6-inches or so for circuit identification. Colors are seldom used for ID in aviation. It is available in multiple types of wire strand preparation and fire resistant insulation covering depending on the application. There is a chart in the FAA advisory circular AC43.13-1B that lists all the different types of composition of the wiring that are available. MIL-W-22759/16 is the most common type used for standard circuits The dash numbers that follow that indicates the wire gauge size followed by another dash for color. The average price is around $0.65 per foot so it can get expensive.

Most folks want the color coded wire but modern auto wire availability is limited on colors and composition of wire strand & insulation. A person would have to special order wire with tracer color codes and would likely have to buy in bulk.

The choices are limited. Tyree Harris is one, the various Bauer offerings, and the Rhode Island offerings.
