Why Artists and Scientists Have Disagreed.
In the realm of art there is no necessity for any purely scientific analysis of sunlight, which is the origin of natural colors, because all the practical value of color is found in its æsthetic effects on the mind, and in order to enjoy these even in the highest degree it is not necessary that we understand the scientific origin of the colors, any more than it is necessary for the artist to know the chemical composition of his pigments in order to produce best effects with them on his canvas. Because of this almost self-evident fact, artists have as a rule been very impatient when any reference has been made to the science of color in connection with color education, believing that color is an exception to the general subjects of study to such a degree that it lies outside of all scientific investigations. Consequently they have not been in sympathy with the physio-psychological investigations which have been prosecuted with such promising results in other lines, when such investigations have been proposed regarding color. While it is not essential for best results in his own work that an expert artist shall know anything of the science of color, still if he is to communicate his knowledge of art to any others except his personal pupils, he must have some language in which to make known his ideas, and on the same grounds if any psychological tests are to be made regarding color, it is evident that there must be some accepted terms in which to record the results, which has not hitherto been the case.
When the well known Newton and Brewster theory of three primary colors red, yellow and blue, was advocated by those scientists there appeared to be something of interest and value in it for the artists also, because with the three pigments red, yellow and blue, they seemed to be able to confirm the truth of the scientific theories regarding the spectrum colors. But the scientists have long been convinced that there is no truth in this theory and have quite generally accepted the Young-Helmholtz idea of three other color perceptions red, green and violet, from which they claim all color vision is produced, and which they call fundamental colors.
This more modern theory has seemed so far removed from the realm of the artists and the colorists that they have not been able to see anything in it of truth or value to them, and so have continued to repeat the old, old story of the three primaries red, yellow and blue, from which the secondaries orange, green and purple are made etc., etc., all of which is the more pernicious when accepted as a correct theory because of its seeming approximation to the facts. And yet there is not in it all any scientific truth on which to build a logical system of color education, and some of the effects which are considered prominent arguments for the system are directly opposed to well known facts in the science of color. Consequently, the artist has failed to gain from the investigations of the scientists anything to aid him in his pigmentary work, and the scientist has not been interested in the æsthetic ideas of the artists which in fact he has generally been unable to fully appreciate, from lack of training and associations.
The system of color instruction here presented for primary grades is based on the results of careful study and experiment for many years in which the attempt has been made to bring the scientist and the artist on to common ground, where they may work in sympathy with each other instead of at cross purposes as has been the case heretofore, and the results with children have already been such as to testify fully to the efficiency of this line of work.
Thus the feeling for color which every true artist has, may be to a certain extent analyzed so that it can be understood by the scientist and recorded for the benefit of fellow artists one hundred or a thousand miles away and in time an aggregation of facts regarding the psychological effects of color collected which will form the beginning of a valuable fund of color knowledge to be increased from age to age.
