It may sound completely odd, but I had to identify many individual RG6 power wires. I decided to use these. After most of the body was cut off, only the neck remained, and they were attached to cables at either end. In other cases, I've doubled the colors on multiple wires. Small enough not to disrupt connections. (I wasn't planning on using colored zip ties, marker strips, etc.) Possibly off-label, but worked well for cable IDs and added a more detailed setup.
