Camouflage/general color designed to blend into bodies of waters using the color blue or even sometimes green, can somewhat blend together with aerial_camouflage. Context is a major indicator but it being dark blue is fairly reliable. Should also be accompanied by the blue_vehicle_paint tag in most instances. Intended for aircraft, watercraft, and even rarely amphibious vehicles but in theory could be used for (usually ceremonial) uniforms. Unrelated to marines or navel infantry.
