This is a wonderful suggestion that I would like to see in the SA. That being said, I do enjoy the night being dark to the point that it is difficult to see without NVGs but as it stands it is devoid of all color. It's as if the second the sun goes down the world turns grayscale. This effect does not produce the apex of foreboding that it could because it's paired with this bland and depressing nightime. It's the fact that the world is so alive that helps immerse one in the horror that is DayZ.
