The simplest element of visual experience is of course found in light and color, the sensation of the eye as such. Yet there is no branch of aesthetic which is so incomplete. We know that the sensation of light or color, if not too weak or too violent, is in itself pleasing. The bright, the glittering, shining object, so long as it is not painful, is pleasantly stimulating. Gems, tinsel, lacquer, polish, testify to this taste, from the most primitive to the most civilized man. Color, too, if distinct, not over-bright, nor too much extended in field, is in itself pleasing. The single colors have been the object of comparatively little study. Experiment seems to show that the colors containing most brightness--white, red, and yellow--are preferred. Baldwin, in his "dynamogenic" experiments,<1> based on "the view that the infant's hand movements in reaching or grasping are the best index of the kind and intensity of its sensory experiences," finds that the colors range themselves in order of attractiveness, blue, white, red, green, brown. Further corrections lay more emphasis upon the white. Yellow was not included in the experiments. Cohn's results, which show a relative dislike of yellow, are contradicted by other observers, notably Major and Baker,<2> and (unpublished) experiments of my own, including the aesthetic preferences of seven or eight different sets of students at Radcliffe and Wellesley colleges. Experiments of this kind are particularly difficult, inasmuch as the material, usually colored paper, varies considerably from the spectral color, and differences in saturation, hue, and brightness make great differences in the results, while the feeling-tone of association, individual or racial, very often intrudes. But other things being equal, the bright, the clear, the saturated color is relatively more pleasing, and white, red, and yellow seem especially preferred. <1> _Mental Development in the Child and the Race_, 1895, pp. 39, 50, ff. <2> E.
