Kia Auto: Black is +12V ???

[Bill]

I took apart a Kia car windshield wiper switch and it had a black wire for
used for +12V DC.

Then in another car for the same wire, they used solid blue.

Also in the Kia, the wire colors used in the switch changed colors past the
first connector.

Is there any standard to car wiring and colors?
