What is meant by color in sculpture and in architecture? It is the law of light and shade, the great law of oppositions which constitutes the charm of nature, the beauty of a landscape at dawn, its splendor at sunset. The color springs from the quality of the modeling; it is the relief which gives the light tones and, by contrast, the dark, in the parts that do not stand out. The ensemble of the intermediary diminutions of light and shade produces the general coloring, whose nuances can be infinitely varied according to the skill of the artist. Modeling is the only way in which to express life; and there is only one thing that counts in sculpture and in architecture--the expression of life. A beautiful statue, a well-made monument, live like living beings; they seem different according to the day and the hour. How beautiful it is to give to stone, through nothing but the values of planes, through the handling of shadow and light, the same charm of color as that of living nature, of the flesh of a woman. In the plastic arts, the color betrays the quality of the planes as a beautiful complexion reveals health in a human being. The antique has shorter planes than the Gothic; it lacks therefore those deep shadows that give to the Gothic such a tormented and tragic aspect. The Greek balances the framework of the human body on four planes, the Gothic on two only. The latter produces a stronger effect, a more _hollowed_ effect, that _effet de console_ which is essentially Gothic. Nevertheless, the shadow that results from it is more sustained than in the antique and nothing could be softer or more full of nuances. The Roman presents an abundance of dark shadows which, in turn, create an effect of heaviness and density. The Greek puts in just enough of them to quicken the general coloring. The Roman gives a flatter effect, which shows nevertheless a magnificent vigor. As for us, we copy these styles endlessly without understanding them, for if we did understand them we should do quite otherwise. We abuse the black, the powerful lines, we put them everywhere; we do not know how to shade light. That is why our sculpture is so poor, why our monuments appear so hard, so dry. The Bourse, the Corps Législatif, might be made of iron with their columns set against a uniform background which prevents the light and air from circulating about them and enveloping them and destroys the atmosphere. This is what people call a simple style. It is not simple, it is cold. The simple is the perfect, coldness is impotence.
