Byzantine IX-XIIIth Century, Florentine XIVth and XVth Century, and the Contemporary Movement. To say that the artists of the movement insist on design is not to deny that some of them are exceptionally fine colourists. Cezanne is one of the greatest colourists that ever lived; Henri-Matisse is a great colourist. Yet all, or nearly all, use colour as a mode of form. They design in colour, that is in coloured shapes. Very few fall into the error of regarding colour as an end in itself, and of trying to think of it as something different from form. Colour in itself has little or no significance. The mere juxtaposition of tones moves us hardly at all. As colourists themselves are fond of saying, "It is the quantities that count." It is not by his mixing and choosing, but by the shapes of his colours, and the combinations of those shapes, that we recognise the colourist. Colour becomes significant only when it becomes form. It is a virtue in contemporary artists that they have set their faces against the practice of juxtaposing pretty patches of colour without much considering their formal relations, and that they attempt so to organise tones as to raise form to its highest significance. But it is not surprising that a generation of exceptionally sweet and attractive but rather formless colourists should be shocked by the obtrusion of those black lines that seem to do violence to their darling. They are irritated by pictures in which there is to be no accidental charm of soft lapses and lucky chiaroscuro. They do not admire the austere determination of these young men to make their work independent and self-supporting and unbeholden to adventitious dainties. They cannot understand this passion for works that are admirable as wholes, this fierce insistence on design, this willingness to leave bare the construction if by so doing the spectator may be helped to a conception of the plan. Critics of the Impressionist age are vexed by the naked bones and muscles of Post-Impressionist pictures. But, for my own part, even though these young artists insisted on a bareness and baldness exceeding anything we have yet seen, I should be far from blaming a band of ascetics who in an age of unorganised prettiness insisted on the paramount importance of design.
