There are questions of the most efficient sorts of lights to implement, and there are also those of the nature of the eye.

Blue light is *harsh* at night because we aren’t supposed to have it at night, naturally it’s only really from the Sun. And blue light is a component of white lights. And blue or white light is shown to affect your melatonin and your circadian rhythm, potentially keeping you awake at night.

The one question of *can we enable people to be awake at night* shouldn’t “outshine” the other: *should we actually cause them to stay awake at night?*
