13. GRAY COLOR - WHAT'S THE CAUSE OF ITS EXISTENCE?

As is known from experience, at low intensity of the falling "light" (at twilight) all the colored substances acquire a dark gray color. This is due to the very low content of visible photons in the emitted-reflected "light beams" in general. Although some their number is still contained, which explains the presence at least of gray color at substances. And besides that, the gray colors in the twilight are not quite gray. Substances are characterized by a subtle hue, which is well evident at higher irradiance. The degree of color discrimination is determined by the intensity of the falling "light".

But, in addition to the gray color that appears at dusk the gray color exists independently - ie it manifests itself irrespective of the level of illumination.

The chemical element will be painted in gray: 1) first, if  the areas with "bare" visible photons of a certain color initially are not present at its periphery that does not allow to create any color sensation (note that the same thing happens in the case the emergence of color of both white and black colors); 2) secondly, very few zones with the Fields of Attraction are present in the external manifestation of the quality of such elements and the magnitude of these Fields is not sufficient, which is the reason for the weak accumulation of elementary particles (including visible photons). Therefore, in the emitted-reflected "light rays" of such elements there is no predominance of visible photons of any quality that are able to create a visual sensation of any color. And in addition, in an emitted-reflected ray there are very few of accumulated free visible photons.

We can assume that the gray color is a light tone of black color. I.e. a zero coloration together with the emission of a small amount of accumulated visible photons.
