I don't see why we should consider -rv be the sign of "night".  Many
people use dark backgrounds for reasons that have nothing to do with
the time of day, and -rv is not such a sign, either.

I think we should ask users who'd want to have a special theme for the
night and that routinely use the dark-background colors what would
they like to see by night.  It isn't enough just to invert the colors,
IMO.
