Cardas Golden Reference - why different colors?

What's the significance of grey shrink versus black shrink on Cardas Golden Reference interconnects?

I also see some that have grey outer jackets, and some that have black outer jackets.

What's up with all the color variations?
It seems that Cardas has changed their markings over the years due to counterfeiting problems. Here are some examples. If you search through the Cardas website, you'll also find info on changes in packaging, and some examples of counterfeits.


Same wire and design underneath the different cosmetics, though? I suspect so.
Yes, same design, just cosmetic changes.
