Although there is no robot rule that covers this color, we do want to keep students using standard color codes so they don't get in trouble elsewhere.

This is dead wrong. It is not the inspector's place to make up rules on the spot based on his own personal opinion just to teach a lesson. There are very few water pipes and GFI's in an FRC robot. If he wants to teach a lesson about house wiring and encourage students to not use green wire then he is free to offer that advice, but you do not make up rules and force teams to rebuild their robot at a tournament because you feel they used poor practice. There are 1000 rules of thumb about good mechanical and electrical practice that are not in the rules and you cannot ask teams to accommodate the pet peaves of every inspector. As a mechanical inspector I would not force a team to put lock washers under their nuts even if I felt strongly that they should, because it is not in the rules and it is not my place to add it. If the GDC intended for a wire color to not be used they would put it in the rules. The inspectors have a checklist for a reason.
