It's because there are not enough colors to go around and the reason you stated. I worked on wire bundles that contained more than a hundred wires sometimes. Often a digital system bus ran from one black box to another, with 32 or 64 wires of digital data.
Schematics are printed black and white. Imagine hundreds of colors represented with color printing or words either one. Black and white numbers are the only reasonable solution. Each wire was stamped with a number and letter suffix. The suffix changed each time the wire passed through a bulkhead.
Carried schematic books
that were eight inches thick and each pair of pages folded out on both sides, stretching to four times the books
cover size. But the conventions used allowed one to actually use the schematics and trace the wires with little trouble.
How the manufacturers organized the stamping of the wire bundles with the numbers must have been a complicated operation, I just fixed the broken wires.
What you guys and gals call rescue
tape, I know as F4 tape.
