In truth, such descriptions are inherently impossible because description, or definition, involves an analysis of content, whereas an elemental experience is irre¬ ducible, that is, further unanalyzable. It follows that very little may be said, in terms of mere description, about the sensational color-qualities, that is, the elemental kinds of color-consciousness. At least four sensational color-qualities (that is, kinds of color experience) are admitted by almost all psychologists as unanalyzable, or elemental. These four are the con¬ sciousness of red, of yellow, of green, and of blue; they are often described, also, as 1 principal colors,’ and for the following reason: If we have a succes¬ sion of color-experiences in the spec¬ trum order, we are certain to recognize Blue Green that the series naturally divides itself Fig. i.

For example, my consciousness of yellowish orange differs from that of yellow by being like both the conscious¬ ness of red and the consciousness of yellow; whereas my con¬ sciousness of olive differs from that of yellow by being like both the consciousness of yellow and the consciousness of green. We rightly, therefore, distinguish between the ele¬ mental experiences of red, yellow, green, and blue, and the other color-experiences, each of which is like two of the ele¬ ments or ‘turning-points’ of the color-square.
