Read something about using embossed labels for this exact reason. Helps if you're colorblind, right? Adds that tactile feel so you can tell by touch too.
Actually think embossed labels are a bit overkill for most home setups. They feel like a workplace safety thing, not something you need for your own cables. The texture can get annoying if you handle the stuff a lot. I just use a label maker with clear, big text. Works fine for me and anyone else who needs to find something.
Ever try labeling things that aren't even cables? I once wrote "dog food" on a bin and my roommate put the actual bag of kibble in there, plastic and all. So the label was right, but the system was totally wrong.
