identifying grounding conductors by national fire protection association code

[stuckagain]

Inside the data gathering Fire panels that are supplied by 110 Volts A.C.
These red panels,one per floor are about 3 feet high x 2 feet wide
The grounding conductor,from the service
equipment,enters each panel as an insulated
green wire.
It is then spliced into about three feet of blue
insulated wire with yellow tape.
This blue wire serves as the ground,and is
connected to all the devices inside the panel
All this wire is visible inside the Panel and does
not leave it
Does the entire Grounding conductor inside
the panel,have to be all green ,or is this present condition acceptable

NEC 250.119 accepts green with one or more yellow stripes as an equipment grounding conductor. Is irt possible it's a poor shade of green rather than blue ?
Secondly, if the fire panels were factory wired, the factory internal wiring would not be required to meet the NEC, but rather the requirements of the listing agency.
To me it's distinct enough and close enough to the 250.119 requirement that I would not be concerned.
