White and black or greys

What Rut says is absolutely true. The NFHS has no formal "power". Most state athletic associations recognize the NFHS as the ruling body and therefore use the NFHS rules. But many of them still exempt themselves from certain aspects of those rules.

This would apply to what officials wear, and is why nobody on this board can answer the question (unless they also live in the same state/work for the same association and know the answer).
