Lecture XVI
The delicacy and sensitiveness of our bodily organisation become evident also by objective and systematic study of light and color treatment for disease. This use of light and color should be more considered in the future than it has been in the past. One must learn to distinguish here, between color which appeals exclusively to the upper sphere of the human being and light proper which has a more objective tendency and appeals to the whole human being. If we simply take the person into a room lit in a certain way, or even expose a portion of the body to the objective influence of color or light—we act directly on the human organs. We then have indeed an influence wholly external. But if the “exposure” is made in such a way as to affect consciousness through the sensation of color—as when instead of irradiation with colored light, the person is brought into a room draped and furnished throughout in a certain colour—the effect penetrates all the organs adjacent to those of consciousness. This “subjective color therapy” always works upon the ego; while in “objective color therapy,” the influence is primarily on the physical system, and through the physical vehicle on the ego, indirectly. Do not raise the objection that it is useless to bring a blind person into the environment of a room furnished in one color, because the patient can receive no visual impression and the result must be nil. Such is not the case. In such conditions the sensory effects which work under the sensory surface, so to speak, are very powerful. There is a difference to a blind person, according to whether a room is entirely red, or entirely blue. The difference is considerable. Take a blind person into a room with blue walls: the effect is to draw or deflect all functional activity from the head to the rest of the organism. If the same person is taken into a completely red room, the effect is reversed; the organic functions are deflected towards the head. From this it is evident that the main effect lies in the rhythm of changing the colour in the environment. The changes of color are the main factor rather than the colors themselves. The isolated influence of a blue room or red is less significant than the contrast in reactions, when the individual who has been in a red environment is brought into a blue, or after being surrounded with blue, into a red. This is significant. Suppose we see a patient, and diagnose the need of improving his upper organic sphere by stimulation of the functions of the head; we should take the patient into a blue room and afterwards into a red. If we wish to act indirectly, through the rest of the organism upon the head function, we should take the person out of a red environment into a blue.
