There is no such thing as "positive wire" or "negative wire". There is only "this wire" and the "other wire" or "1" or "2" or "A" or "B".
You decide if you wish to consider the stripe to be red, black, positive, negative, etc.
FYI, sometimes wire isn't striped ... sometimes there is a physical ridge in the insulation ... sometimes there is a thread inside the insulation next to the wire ... sometimes one conductor is silver and the other gold. It is just a way to identify one conductor from the other.
FWIW, I use the stripe to indicate "positive/red/A/1/thread/gold/ridge" in my own hookup.
It doesn't matter!
Just be consistent
