Color range is a concept introduced in psychophysiology and physiology of vision when studying the characteristics of human color sensations. The color range is a collection of different color stimuli that can be represented as a continuum from light to dark or from pure red to pure blue. As has been established in experiments, color has different physical characteristics and can evoke different emotions and perceptions in people, depending on their individual characteristics of color perception.
Let us consider the essence of the phenomenon of the color series. In nature there are several thousand shades of color and every combination of white, black and all shades of gray. Between these colors are all the other colors of the spectrum. By “all others” we must understand each color separately and all its shades. They are called non-spectral. There are two types of them - subtractive and additive. Subtractive is, in fact, black itself; other colors are obtained from a combination of primary colors. Additive consists of the colored lights of a fluorescent lamp, the remaining colors are illuminated by different light filters - red yellow blue green gray purple red and so on. The predominance of one is warm tones, the other is cold. Here, the primary colors glow due to the brightness of the glow; when mixing additional colors, the result is not a color, but a glowing neutron or a nuclear reaction. To obtain a spectral color from combining two additive ones, simply do not remove the necessary filters from the light pu
