I came up with a color code based on the wiring: Red for Power Only, Blue for USB 2.0, Green for USB 3 (the ones with the extra pairs connected). I use paint pens to mark every cable I come across with this code. Generally speaking, only the Green ones have special PD emarker chips.
It doesn't cover every possible configuration, but it's good enough for when I'm like "I need a USB cable" vs "I need a good USB cable"

- 3RTB297 2mo agoAs much as the original author bemoans having to do the labeling themselves, 99% of people don't care or don't have such a mix of cables as to make it a challenge to find one to suit the task. If you care, then care enough to do small, practical things for yourself. A little loop of tape. Paint marker. Even just sorting them into drawers/boxes/whatevers by type.
