I recall coming across the color guide for the various features, like blue for USB3, and red for… power delivery, maybe?

But then one day I was on AliExpress or Alibaba or something and seeing that you could just buy cables from some manufacturer with whatever color you wanted. And I lost faith in the reliability of color id for cables.

I'd go with yellow, like how we draw lightning.
