A suggestion / idea: Nighttime 'colours'

While it would mostly be eye candy, FoolTrottel's point about human night vision and lack of color vision is spot on.

Ideally, there would be some way for a pilot to "gain" further night vision if he's exposed to relative darkness for 20 or so minutes, as well as some temporary loss of night vision if he's "dazzled" by bright lights (e.g., searchlights, nearby gun flashes, flares or incendiaries).
