It looks like copper rust, but very strange and unlikely.

Or caused by a reaction of the cord thread material with hand sweat, lotion, sanitizer, hair gel, etc.
It seems that it's only happening at that part of the cable near the connector, which is the most handled part.

That may be it. I use wired in-ears with exposed cables that turn blue/green just like this over time. The cable is probably all green underneath at this point and its seeping through that outer cover.

The thing is that the AVP cable is too new for this to happen. And the cables shouldn't be exposed inside.
Something else is happening there.
I would suggest passing a white paper tower in that area of his head to see if it gets stained.

It will depend on the amount of humidity this part is exposed to. For the much thinner headphone cables I was talking about it usually takes a few months before they start to turn green. And if the copper cable comes in contact with the outer sleeve at all then that may also be enough to produce this kind of result.

Perhaps there's a totally different explanation though. I don't have this kit myself, just judging from the picture. However to me it does look too even to be a stain from hand contact.

This part of the cable is rarely ever touched. I almost never disconnect the battery. This part sits atop the plastic and shouldn’t come in contact with skin much at all.

I've had this happen to a few cables (3-4). For me it has always appeared at the ends of the braided USB-C cables, coming out of the connector. I assume it is some sort of oxidation from metal inside the connector housing. I initially thought it may be from dirt or the oils in my hands etc, however that is typically a light brown or gray color and this also happens on ends of cables I quite literally never touch. One cable I opened and immediately plugged in behind my couch and never touched again until discovering it developed this discoloring.
