Joe,
110.3 has absolutely nothing to do with this issue. Again, you have not provided any code citations to support your position.
Please respond to these questions.
1) Is a grounding electrode conductor an "grounding conductor"?
2) If it is, please tell me how 310.12(C) can be complied with when you are using a color other than green for the GEC?
3) If the GEC is not a "grounding conductor", then what is it?
Don
