> Our eyes are the least sensitive to it so it requires more light (which means more overall brightness, which actually makes your night vision worse and limits visibility of everything not lit, because your iris closes more) and it provides poor visibility/contrast and no color vision. This does not match very common naval practices, nor my experiences. I believe the underlying mechanism is that the iris responds much more strongly to blue light because that is more prevalent in daylight. Specifically this is about using red light to shine on things to see them. I could imagine that has very different requirements from the color of text on a HUD.
