How do add colour to a black wire to help identify

[OM2]

A bit of a random question...
I have many charging cables... all black.
I want to add 'something' to help me identify which cable is which just by glancing.

Electric tape! That does the trick
Except... it comes undone and the stickiness starts opening up over time

Could I try anything else?

Thanks.

That was my first thought then realised plugs may need cutting off the end first

Thanks guys.
I wanted something that will cover 5cm at least say, so none of those any good.
Just had a thought... maybe vinyl stickers would do the trick?
I've got loads of samples sent to me... just need to find

I use a simple label printer (£15 at Aldi), print twice then I can fold the double label over the wire and stick it to itself.
