During dark moonless nights the eyes are useless and the ears and other senses take over the heavy burden of reassuring - a burden which they in fact cannot carry. Therefore the dark nights belong to the invisible whispering ghosts and frightened people crowd together inside their sheds.

At dawn light arrives gradually, colours later than black and white and grey. Likewise, the rainbow colours do not arrive until sun shines again.

Light and sound are subdued by rain. When sun arrives in the morning the birds start to sing again, and according to South American myths their colours also arrive with the death of the great watery monster.

Ghosts have no colours and they do not talk loud, they whisper like the sea shells on the beach.
