Someone who is familiar with reddish-green should be in a position to produce a color series which starts with red and ends with green and which perhaps even for us constitutes a continuous transition between the two. We would then discover at the point where we always see the same shade, e.g. of brown, this person sees brown and sometimes reddish-green. It may be, for example, that he can differentiate between the colors of two chemical compounds that seem to us to be the same color and he calls one brown and the other reddish-green.

Someone who has learned to find or to mix a shade of color that is more yellowish, more whitish or more reddish, etc., than a given shade of color, i.e. who knows the concept of intermediary colors, is (now) asked to show us a reddish-green. He may simply not understand this order and perhaps react as though he had first been asked to point out regular four-, five-, and six-angled plane figures, and then were asked to point out a regular one-angled plane figure. But what if he unhesitatingly pointed to a color sample (say, to one that we would call a blackish brown)?

Intuitively, some colors "feel" like primary colors more than others

he learn the correct use? — He constructed an ideal use from the ordinary one. And that is not to say a better one, but one that has been refined along certain lines and in the process something has been taken to extremes.

Your ears may be at rest in total silence, but your mind usually isn't, because the slightest noise can be be startling. The purpose of the entire apparatus of hearing is to discriminate between things that make noise. If you want the discriminating component of your hearing apparatus to be rested, "white noise" is probably better than total silence. Similarly, if the discriminating component of your color-seeing apparatus is to be fully rested, gray is better than total darkness (black) or its opposite (white).
I shall explain what "opponent cells" are and how they function at a later stage. For now, it is enough to know that opponent cells discriminate lightness from darkness, blue from yellow, and green from red, and they are all at their default — "in between" — setting when we are looking at a neutral middle gray.]]>
