Geometrical forms have already been so definitely analyzed by the science of mathematics that if destroyed to-day these solids and surfaces could be reconstructed at any future time from written or printed directions. But suppose all material samples of color to be lost, it would be impossible by the ordinary system of color nomenclature to even approximately restore a single one from written or verbal descriptions.
Color is one of the first things to attract the attention of the infant, almost as soon as a sound and long before form appeals to him, so that a collection of colored papers will often prove more interesting and instructive than a picture book to the baby, while the graduate from a two year's course in the kindergarten may have a better color sense than is at present enjoyed by the average business or professional man.
If we could determine the colors used by the great masters in the past, we could add much to our knowledge of the fine arts; and if we knew what colors Chevreul, the master dyer of the Gobelins Tapestry works, refers to in his writings, and which he indicated by hundreds of numbered samples filed away in his cabinet, we should in this generation have a wonderful fund of information to increase our knowledge of harmonies, on which to base our study of color in the industrial arts.
But alas! the paintings of the old masters have faded and the great dyer had no language in which to describe his colors in his writings, and therefore it is claimed that little or no advance in color perception has been made in modern times, if indeed we have held our own. The further assertion is made that those semi-civilized nations whose drawings are the least artistic greatly surpass us in natural color perceptions. If color is the one thing in which we are deficient and in which we are making no advance, is it not necessary that we adopt a new line of operations for our color instruction in the primary grades? It is self-evident that in primary work highest art is not expected in either literature, music, drawing or paint-
