I agree with CTWireman. Except that I don't mind the ground conductor being green/yellow. In fact, I think it makes a very good contrast with the black and the white conductors for use in flexible cords. Isn't there a whole colorblindness issue where there are some people who can't distinguish green versus red? Since I have numerous things that weren't made for the US market, I'm probably one of the few Americans now comfortable with the European "harmonized" scheme.

I've noticed that the harmonized cordage is ever so slowly catching on in the USA (brown live, blue neutral and green/yellow ground), particularly in imported cords (like some Chinese computer cord-sets I've dissected). Same holds true with the wiring inside some computer power supplies.

Next time you find a computer in the garbage, take the power supply apart and you'll see that most of the times the wires connected to the power inlet follow the European color coding. [Linked Image]
