What color B5 or B7?

My build sheet list the trim as b7 and the body paint as b5. I want to repaint my steering column and touch up some of the metal areas inside the car. Would I use b5 or b7 to match the inside? Does that mean the inside is b7 or that just the inside cloth/leather is b7 and everything metal is b5?

Thanks!
