For what it’s worth, the terminal screws on US outlets and replacement plugs usually actually are color coded. The screws for the hot (black) wire are gold or brass, and the screws for the neutral (white) wire have a silver finish. The ground screws are usually anodized green.
You’ll actually find green colored ground screws in tons of devices, not just outlets and plugs.
What resistance? The screw itself is not intended to carry any current. It just keeps the ground ring or whatever it is in contact with the terminal or the chassis of the device in question.
color-coded screws? wtf

wouldn’t that add resistance to ground path (avoidably)
