I have also had an official tell us that a mouthpiece unattached to the facemask cannot be clear white. Then had another official tell us that no mouthpieces (attached or unattached)can be clear or white. What is it?

Here is the exact wording..

The mouthpiece must be an intra-oral device of any readily visible color. It must not be white.or transparent. It must be made with FDA approved base materials and cover all upper teeth. It is recommended that the mouthpiece be properly fitted.
