Perhaps you will say--Why this is only a repetition of what was said about the painting of reflections of light and the shadows on the blue skirt! You are right. Then--why, you ask, this new term--values? Well, it was when the modern man discovered that the painting of these reflections and shadows could be made a means of producing harmonies of color; that, indeed, harmonies could be produced out of the reflections alone, that they invented this new name. They had discovered a new principle of harmony, depending upon the varieties of light on color, and they gave to these varieties the new name of values. Not that the principle was really a new one. It was an old one discovered by Velasquez and at the same time by the Dutch--Vermeer among them.[10] But about 1860 some modern artists from studying the works of these men made a new discovery of the principle.
