Yellow with green stripe as EGC?

My understanding is that green is used as a hot in traffic light applications, where the wire colors match the light colors. There will also be tracer colors to organize which signals the wires are going to.

Looking at the picture, that's 18ga type MTW/TFFN so it might very well be intended for traffic control panels. The OP is using it for control panels, not building wire.

That's what I thought I was seeing but I wasn't sure.
 
i know yellow is a hot color but ... Wash. Amended Code 296-46b-230 ss 043 (9) "In addition to the methods allowed in the NEC, the grounded service conductor is permitted to be identified with a yellow jacket, or with one or more yellow stripes". It is only referring to a service, true, however it is talking about a solid yellow jacket being a grounded conductor. I think we've all run into URD with a yellow Neut. by now.

Most tracers i have seen are on white wire and only blue or red (that i've seen). that being said, it would be a sad day that i ever used this yellow wire with a green tracer for a hot conductor. It might not be the best, or even legal, wire to use for a ground, but that is really the only use that I can see for it. Maybe it isn't meant to be used in a building or something like that. Might be for appliances or, well who the heck knows. somebody here will. traffic control sounds as good as anything else.
 
Here is another Yellow conductor with a Green stripe EGC in a new listed fixture.

That looks like what the utility guys use here for tracer wire.

We use solid green with a ylo trace for IG grounds.

Yeah, I’ve seen green with a different color tracer for isolated grounds. I bet you’re right on that color being for a locate wire, probably gas since it’s yellow.
 
In addition to the NEC, NFPA 79's requirements for the grounding conductors and terminals:

13.2.2.1* The color GREEN with or without one or more
YELLOW stripes shall be used to identify the equipment
grounding conductor where insulated or covered. This color
identification shall be strictly reserved for the equipment
grounding conductor. GREEN shall be the predominant color
when used in combination with one or more YELLOW stripes.
Exception No. 1: Conductors with green insulation or insulation that is
green with one or more yellow stripes shall be permitted to be used for
other than equipment grounding purposes where all of the following
conditions are met:
(1) The conductor is part of a multiconductor cable.
(2) The multiconductor cable containing the conductor contains only
circuits supplied from a source limited to less than 50 volts.
(3) The multiconductor cable containing the conductor contains only
circuits supplied from a source limited to no more than a powerlimited
Class 2 energy level.
(4) The conductor is reidentified at all accessible locations, or the
multiconductor cable is part of a listed assembly

8.2.1.3.3* The equipment grounding conductor terminal
shall be identified with the word “GROUND,” the letters
“GND” or “GRD,” the letter “G,” the color GREEN, or the
symbol shown in Figure 8.2.1.3.3; in addition, the letters “PE”
shall also be permitted to identify this terminal.
8.2.1.3.4 Where an auxiliary grounding electrode

8.2.5.2* The equipment grounding conductor connecting
points, other than the equipment grounding terminal, shall be
identified by the color GREEN, by the bicolor combination of
GREEN-AND-YELLOW, or by use of the symbol shown in
Figure 8.2.1.3.3.
