Have you actually seen this as a written requirement?
Or is it just that is what is expected?

I'm curious what colors folks use for the switchlegs when they have a 480/277 system and a 120/208 system in the same building.
Anyone use the HV colors for LV switchlegs, and vice versa?

Might happen..
We have done jobs in MC where we tried to have the right color MC cable on site....it was a nightmare.
I need orange/gray 12/2 MC for this switchleg....red/white MC for this receptacle.
I think you can guess what happens toward the end of the job....

I had a an inspector forbid grey as a netral in either 120 or 277v , He cited "thats not Natural Grey" Well one of they guys I worked with went to the corner paint store and picked up a paint chip that read " Natural Grey"
Showed it to the inspector . The inspector was pretty miffed proceeded next to spend the most time I had ever seen on a job trying to find something. Te only thing he could find was a strut clamp that was not fully tight. I bet that guy was steamin the whole day.

natural grey
natural grey
worked for a "chief inspector" one time held fast to the same ruling.
Turned out, "Southwire" backed him. "ole timers" much OLDER than me are getting scarce, but some might shed light. as i recall, "natural grey" was a term used by wire mfgs for an insulation color from a type insulation prior to the thermoplastics when they couldn't obtain pure white. So, in fact, the code language applied to this "off white" the mfg called natural grey which was different from grey.

Greg,

It has been proposed a number of times and has been soundly rejected by the CMP.
