A suggestion / idea: Nighttime 'colours'

perhaps 5 classes sunrise midday evening dusk and night to make it "realistic" but that's a big ask.

Actually, it is done that way already. When you got 32 bit enabled, the last 8 are used for lights. You could see this by generating TGA files, and opening them with a picture editor that support multi layered images. A screen shot at night will look full daylight just by removing this last layer.

Problem is that colors are being darkened, but not turned into B/W.

It could be achieved by establishing a threshold on the darkening layer. When lights go below X, all colour levels are equalized, achieving a true night sight.
