Why would that only be for newbies?The old way is to use white cloth medical tape and a marker, but that's only for newbies....
If you are looking for cheap, I don't know. If you want to make some, there are a number of cables that are available in colors. The Canare cables are nice and colorful. Markertek has em and connectors that aren't too expensive. Just an option if you don't find what you need. Canare L-4E6S is a nice cable and 10 colors by the foot. There are others on their site. Good company to work with.
