The color key is given in that selected hue which influences to a greater or less degree all the colors, even when these make violent departures in the scheme of harmony. Solicitous only of the quality of unified color, the majority of these painters (though this frequently does not include Mr. Whistler himself) concern themselves wholly with that thought, employing their pigment so directly that the vibration of color is sacrificed.

The production of this vibration is by agreement on the part of all great colorists impossible through impasted color or that applied flatly to the surface, which they declare cannot be as [pg 274] powerful, as significant or as beautiful as that which vibrates, either by reason of the juxtaposition of color plainly seen, as with the impressionists, or of its broken tone, or by virtue of the influence of a transparent glaze of color which enables two colors to be seen at once.

The last method is that of Titian, the second in combination with the last that of Rembrandt in his latest and best period, the first that of Monet, which contains the principle of coloration in its scientific analysis. The chasm between these men is not known in any such degree as a superficial notion of their respective arts might presuppose. The real disparity in color presentation exists between all such painters and those who paint directly on white canvas, neglecting the influence of the undertone and the enrichment which enters into color by glazes (transparent color).

Such painters may be able to represent most faithfully the true tints of Nature but not the true impression, for Nature is always expressive of that depth and strength which lies far in and which the painter of “quality” insists to render. To him it is that something containing the last word of a thorough statement, and without it the statement is a surface one.

Technically, it may mean the labor of many repaintings, of color glazes, and of procedure from one process to another, so that the first statement on the canvas becomes the general but not the final dictum. Through these the work takes on that unctuousness of depth and strength [pg 275] by which one experiences the same thrill as through the deep reverberations of a musical tone from many instruments, simple tone being producible by one instrument. Practically, it is the pulsation of color in every part of the picture felt by either the play of one color through another or by such broken color as may be administered by a single brush stroke loaded with several colors or by a single color so dragged across another as to leave some of the under color existent.
