I redid all of my cables, sort of, and color coded the Neutrik XLR with these:
Neutrik XXR-2 Colored Coding Rings for XX Series Connectors - Red
They not only help me identify cable length, but for mics, I give the same color to the same band member each gig.
Whole slew of them for different types of XLR, as well as 1/4"
Markertek - Search Results for colored neutrik
Truth be told, no real issue with 1/4" for me, as they're individual instrument cables - change the connector color, or for me, the cable color.
BTW, not that I have any horse in Canare's race, but I use both the GS-6 for instrument cable, and the L-4E6S for balanced cables, in different colors. Yeah, mostly black, but I like Red, and my guitar player likes orange for his MI cable.
Wrapped properly, and small velcro for each cable, and a large velcro to wrap at least 2 together of similar sizes/color/whatever, stacked into a backpack (just because my kids get new ones for school each year, I take "last year's" one).
Note: the BEST thing about the colored XLR, especially if you're running direct to the board, is you no doubt know which channel any given player is on, whether coming from a mic or DI.
