Can anyone help with describing the shade of blue for Patrols which is deemed "correct". I am trying to describe to a uniform supplier on the other side of the country what colour they are supposed to be. Calling them "blue not blue-black", "No. 1 Blues" and sending pictures isn't cutting it. Is there a NSN or a colour chart or something available. At the cost of custom set I want to get this right the first time. One of my peers had to send his back because they were so dark they looked black.
