I have used a knot too, but that doesn't work as well for 
heavier gage leads.

I have used a similar method since 1973 when working in an 
electronics lab,
but even simpler!

I tie a knot in the positive.
This has the advantage, when using flat connectors, that 
they lay flat on
the front of the power supply.

Subject: Tactile Marking for Power Leads

A long time ago, I began marking the positive lead of all of
my equipment. At first I did this by wrapping a twist tie
around it. Now, I use a small zip tie that is pulled tight
around the lead an inch or two behind the ring terminal or
whatever is on the end of it, and then cut off as close to
the fastener as possible. This gives me an easy tactile
indication of the positive lead should it be necessary to
remove or re-attach it when there are no working eyes
around.

By only marking the positive lead on each power cable, you
know which lead is in your hand when your at the power
supply end of the cable.

Every ham, blind or not, should do this.
