Had I the heavens’ embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half-light,
I would spread the cloths under your feet:
But I, being poor, have only my dreams;
I have spread my dreams under your feet;
Tread softly because you tread on my dreams. William Butler Yeats
Those who believe that during the night all cats are gray and all images black, can be cheated. The lighting seems low, the visibility is good or bad and what we perceive is more or less easily recognizable.
The reduced light at night creates its own flowers: The night dissolves the borders between the imaginary and the real.
