In marked contrast, for the most part, appears the characteristic feeling-tone for our chosen shade of _yellow_. Almost universally subjects find such words as these descriptive of the feeling here in question. It is cheerful, brisk, pleasant[84] also, bright, gay, light, sprightly, merry, jovial, easy to get, pleasantly irritating, stimulating, stirring, spurring, thrilling, invigorating, and produces agreeable discontent. It is jolly, nice, trim, neat, awakening, full of the sense of motion, soaring, and arouses a feeling of welcome strain, of pleasure in action, of alertness and self-assertion. Here, in contrast for the most part to the red, there is no feeling of sinking into the color. The impulse rather is to be free, to enjoy motor expression, even if of some vague sort. There is a _felt_ necessity to do something, a "joy of overflowing or of exuberance," it is called. There is little present here of what we mean by a suggestion of sensual richness found above in the feeling for red. Here there is less of amount of pleasure, but much more of the general activity element. Some subjects feel the demand for greater saturation, and occasionally it is unpleasant for just this reason apparently. Subjects C and B frequently reported this. They think the feeling would be more "stable" and "grave" and "secure" and "soothing" and one would not feel "unruffled," if it could be "toned down." Most of the subjects, however, think that it belongs to the ultimate elemental feeling for yellow that it should have just this distinguishing characteristic. It is more difficult to describe the feeling for _green_. It is almost always agreeable. Two subjects, however, never like it. Sometimes it is somewhat soothing in character, but more often it is exciting. The feeling seems to be between that for red and that for yellow, partaking on the whole of the characters of feeling for the latter rather than the former. For all subjects associations tend to color the feeling-tone for green especially, and hence introspection for the feeling of pure color is doubly difficult. The most prominent partial feeling-tone for it is "irritating."[85] The agreeableness or disagreeableness of this stimulating character is particularly inconstant, varying greatly for the same subject, as well as for different subjects.
