I had a guy wrap his black neutrals with duct tape.

I didn't know silver was an approved color.

I'm looking at a roll of duct tape right now that is closer to gray than it is to silver.

I'm not talking about the chrome shiny tape. . I'm talking the grey duct tape that guys use for just about anything under the sun. . The NEC doesn't require white. . Grey is acceptable.

Extra kudos for creativity !

If I were following behind him, I would be wondering what kind of skinned or damaged insulation they were covering with the duct tape.

At least duct tape would stick.

Marking tape can cover nicks and damaged insulation as well as duct tape.

I'm unsure of the reason it is in the Code, but on smaller ampere circuits where your grounded and grounding conductors are the same size or close to the same size, (as the phase conductors) I think it makes a lot of sense. I can see a positive point to looking at conductors in a panel or box and immediately distinguishing the "hot" conducturs from others without tracing them to an origin (in theory at least).
On your larger circuits the reduced grounding conductor is fairly easy to spot.. more so than an equal size conductor.

"immediately distinguishing"
I was complaining about this thought on another thread, the one it which I expressed my hatred for grey conductor insulation manufacturer dye coloring.

I see 3 versions of grey out there and I hate them all

1] the grey that you can't tell if it's white unless you put it right next to a white. . Is it the neutral for the 120v system or the 277v system ? . You can't immediately distinguish.

2] the grey that looks so dark that you're not sure if it's a really flat black or a grey. . 120v hot black or 277v neutral grey. . Make your guess.

3] the grey that's circuited with a grey-brown. . Why do they make grey-brown anyway ? . What's wrong with chocolate brown ? . You've got 277v between the grey and the grey-brown, but which one is the grounded conductor ? . Where did I set that flash light ?
