    s A, B, and C. The inspirational 1922 report marked a shift in the treatment of color to a scientific one, defining color in the following terms:
Color is the general name for all sensations arising from the activity of the retina of the eye and its attached nervous mechanisms, this activity being, in nearly every case in the normal individual, a specific response to radiant energy of certain wave-lengths and intensities.
