Green ground bus bar or green inset screws?
Is there a US code requirement (NEC) that requires the ground bus bar in a panel to be green, or use green screws? Or specifically a local CT requirement? No speculation please just the facts. Need to know for sure.

I have never see a green ground bar. The fact it is not mounted on insulators is a way of identifying it isn't a ground bar. Why do you ask.

I had an electrician tell me (providing an estimate), that my grounding buss bar in my sub would have to go since it was not green. I'm not an electrician, but I had never heard of such a thing, and after checking with a local electrical supply house and city inspector, they hadn't either. I know that device grounding screws are green, but buss bar? Not sure why the electrician would mention something so bizarre. Needless to say, I thought his estimate was way too high for the work I was asking him to do, and believe now he was trying to blow smoke up my you-know-what. Odd.

Eaton makes them and I have seen them around. They are still not required under the NEC. It might be a local code. To find out, give the local AHJ a call.

Aha! The ground bar with green screws liveth! So there is one. That's what he was referring to. I see how that easily would identify a ground bar, but is it really necessary? I'll be sure and double check with my electrical inspector on Monday. I'd be surprised if it was local code, since I did have my electrical wiring signed off a couple of months ago and no mention was ever made of a ground bar with green screws by my inspector.
