Haze gray is a paint color scheme used by USN warships to make the ships harder to see clearly.[1][2][3] The gray color reduces the contrast of the ships with the horizon, and reduces the vertical patterns in the ship’s appearance.[4] It is the color of USN combatant and auxiliary surface ships, in contrast to the dark gray or black color of submarines, the bright colors of ceremonial vessels and aircraft, or the white of hospital ships and some U.S. Coast Guard cutters.
Note that Twonks is British, and the Brits typically use a slightly different gray, with a more greenish cast (historically, IIRC, they selected paint color varying based on theater of operations, but I think that in practice, “warship gray” acts as more of a uniform to indicate that something is warship today than to reduce visibility, as in actual combat ranges in 2026, visual detection probably isn’t going to matter much).
