appreciate and enjoy the colour itself without the addition of form, which would seem to be an unnecessary complication. The whole question of the introduction of decorative form is, however, a very interesting one and might well be explored farther. In music we are perfectly satisfied with compositions which do not express definite ideas, and in colour there seems to be no reason why this should not also be so if our colour sense is sufficiently developed. If stringed instruments had never been invented, could it have been for a moment supposed that a whole audience would sit spell-bound under the sounds produced by drawing a horse-hair bow over a tightened gut-string without definite words or ideas attached to such sounds? It is simply the insufficient training of the colour sense in many people that makes them demand form in addition to colour, or prevents them from enjoying colour for its own sake.
