NEC=Logical?...not at all.
We've had to replace the grey marking tape on a job's 480/277 feeders (about 20) to get it to pass a final inspection. I thought it was a BS call, but the inspector (unfortunately correctly) stated "I don't write the Code, I just enforce it."
This little lesson cost us a day on completion due to the re-inspect necessary.
By the time the electrician's filthy hands were done with the white tape, it was grey anyway...S
