A wire type can be bare or any color other than white or gray. Same as a GEC.
Thats my question if the screw has to be green why not the wire. BTW I don’t think it specifies it cant be any color including white or grey at least for sbj

The function of the screw, because it is often located with other screws, may not be clear without the green identification. The function of a wire type system bonding jumper should be clear to any electrician base on its location in the circuit and its connection point.
250.28 does not address the color of a system bonding jumper.
As far as it being white or gray, 200.7(A) prohibits a white or gray conductor from being used for any purpose other than a grounded circuit conductor.
The language in 250.119 would permit a conductor with green insulation to be used for the system bonding jumper.

Don gave you the applicable code sections. The code is specific regarding using a screw as the MBJ requiring a green finish.

Another reason for the system bonding jumper screw to be green is so the inspector can identify a system bonding jumper installed in other than the service panel.
