Are these genuine/correct for a HZ ute?

[Taily]

i thought the jacks were blue?? the jack looks right to me, ive got a few and they look the same, but there not gold

I've seen blue, red (orange sort of shade), and black. Not sure what goes with what, but have my original one (black) in my HJ ute.

Wonder if it was a plant specific (ie different local supplier) thing or if different batches (ie small design changes) were different colours etc....?
