My preferred paracord vendor offers "grab bags." These contain around 30 lengths of paracord, each length being about five feet (152 cm) long. The scrap below was from one of those lengths.
I didn't think it was anything overly special, until I cut it and noticed one of the internal strands (at far right in the picture) was yellow and black. This strand has a reflective tracer. It wasn't commercial grade 550, but Mil-Spec! All the paracord I've used aboard ship or military shore facility has had that tracer.
Naturally, the lanyard I made went on my Farmer X.
