The sap rises and, itself a mixture of elements, flowers in a mixture of tones; the trees, the rocks, the granites cast their reflections in the mirror of the water; all the transparent objects seize and imprison colour reflections, both close and distant, as the light passes through them. As the star of day moves, the tones change in value, but always they respect their mutual sympathies and natural hatreds, and continue to live in harmony by reciprocal concessions. The shadows move slowly and drive before them or blot out the tones as the light itself, changing position, sets others vibrating. These mingle their reflections, and, modifying their qualities by casting over them transparent and borrowed glazes, multiply to infinity their melodious marriages and make them easier to achieve. When the great ball of fire sinks into the waters, red fanfares fly in all directions, a blood-red harmony spreads over the horizon, green turns to a deep red. But soon vast blue shadows chase rhythmically before them the crowd of orange and soft tones, which are like the distant and muted echoes of the light. This great symphony of today, which is the eternally renewed variation of the symphony of yesterday, this succession of melodies, where the variety comes always from the infinite, this complex hymn is called colour.
