Green with yellow tracer?

[612278]

Hello everyone-
In the NEC Art; 250-119 (1999) It states under "identification of equipment grounding conductors" that A continuous outer finished that is either green or green with one or more yellow strips. Now the question. Is the yellow a standard of some sorts for say bonding? Or some sort of secondary grounding for ISOs? Why couldn't also use green with red strips? Seem petty but there's got to be a reason for yellow.

The reason is because the IEC ground wire is green with a yellow stripe. The code allows this so you can get equipment in from Europe and they can use their std ground wire color.

Green wire with a yellow stripe in conduit and another equipment ground is present this would be an isolated ground.
