You are only allowed to reidentify white wires in cables and cords where you are stuck with the way manufacturers put them together.
I am sure you could find Romex with a red and black wire (no white) but that is not going to be readily available.
If you are pulling wire in pipe you should be using the right color. Hot wires can be any color but white, grey or green and they commonly get additional reidentification to help figure out what is going on.
You are also “stuck” when it comes to large sizes since they are only going to come in black in most cases so you will see them reidentifed white or green.
