Hering's Theory of Color Vision

Hering's theory of color vision was proposed by German physiologist Ewald Hering in the late 19th century. It describes the mechanism of color perception in the human visual system.

According to Hering, there are three main processes of color perception:

1. The red-green process is responsible for the perception of red and green colors.

2. Yellow-blue process responsible for the perception of yellow and blue.

3. White-black process responsible for perceiving the brightness of an object.

These three main processes are mutually antagonistic - activation of one suppresses the other. For example, stimulation of the red-green process suppresses the activity of the yellow-blue process.

The combination of the activity of these three processes and their interaction allows us to perceive the full variety of colors. Hering's theory provided an important explanation of the mechanisms of color vision and is still widely used in science.

Hering's Theory of Color Vision is a theory proposed by German physiologist, Ernest Hering, which describes the process of color perception by the human eye. Hering believed that color is perceived not only by the eye, but also by the brain. According to his theory, color arises as a result of the interaction of the light spectrum with the eye receptors, which are located on the retina.

Hering's theory is based on the principle of contrast. He argued that our brains perceive only certain colors, and that these colors are perceived in
