One point, however, the question of colour, still remained unsolved: as the preceding generation took their form, so these painters took their colour, not from nature, but from the treasury of old art. Courbet announced it as his programme to express the manners, ideas, and aspect of his age--in a word, to create living art. He described himself as the sincere lover of _la vérité vraie_: "_la véritable peinture doit appeler son spectateur par la force et par la grande vérité de son imitation_." But one may question how far his figures, and the environment of them, are true in colour? Where there is a delightful subtlety of fleeting _nuances_ in nature, an oppressive opaque heaviness is found in this modern Caravaggio of Franche-Comté. He certainly painted modern stone-breakers, but it was in the tone of saints of the Spanish school of the seventeenth century. His pictures of artisans have the odour of the museum. The home of his men and women is not the open field of Ornans, but that room in the Louvre where hang the pictures of Caravaggio. _Alfred Stevens_ made a great stride by painting modern _Parisiennes_. Whereas the costume picture had up to his time sought the truth of the old masters only in the matter of the skirts which the fashion of their age prescribed, Stevens was the first to dress his women in the garb of 1860, just as Terborg painted his in the costume of 1660 and not of 1460. But the very atmosphere in which the _Parisienne_ of the nineteenth century lived is no longer that in which the women of de Hoogh moved. The whole of life is brighter. The studios in which pictures are painted are brighter, and the rooms in which they are destined to hang. Van der Meer of Delft, the greatest painter of light amongst the Dutch, still worked behind little casements; and in dusky patrician dwellings, "where the very light of heaven breaks sad through painted window," his pictures were ultimately hung. The old masters paid special attention to these conditions of illumination. The golden harmony of the Italian Renaissance came into being from the character of the old cathedrals furnished with glass windows of divers colours; the half-light of the Dutch corresponded to the dusky studios in which painters laboured, and the gloomy, brown-wainscoted rooms for which their pictures were destined. The nineteenth century committed the mistake even here of regarding what was done to meet a special case as something absolute. Rooms had long become bright when studios were artificially darkened, and artists still sought, by means of coloured windows and heavy curtains, to subdue the light, so as to be able to paint in tones dictated by the old masters. Stevens shed over a modern woman, a _Parisienne_, sitting in a drawing-room in the Avenue de Jena, the light of Gerard Dow, without reflecting that this illumination, filtered through little lattice-windows, was quite correct in Holland
