purple color does not exist .. What is the story? – ryan

A recent scientific study revealed that the purple color is not a real or physical color, but rather an optical perception produced by the brain.

The researchers explained that the purple color is an innovation of the brain to explain a mixture of red and blue light, according to the British newspaper “Daily Mail”.

The brain also faces difficulty in treating these two colors that are incompatible in the visible spectrum, resulting in their awareness of purple.

To exceed this contradiction, the brain reorganizes the optical spectrum in a circular shape, which makes it connect between the red and separate blue colors, and this merger results in our awareness of the purple color.

Although we see it clearly, the purple color does not represent a real physical existence, but rather a nervous mechanism for a solution that contradicts visual signs.

The eye contains specialized cells called cones, which are responsible for colored perception.

There are 3 types of these cones, namely: the first type responds to blue and purple light (referred to as S), and the second type senses the green and yellow light (referred to as M), and the third type is red and orange light (referred to as L).

And when the light enters the eye, these cones are activated and send signals to the brain, which determines the color based on the mixture of these mentioned signals.

In natural conditions, this mechanism allows the brain to distinguish between more than a million colors, including composite colors such as turquoise and green blue, however, the matter is different for purple color, as it has no wavelength of its own.

To overcome this, the brain depends on combining the signals from the cones sensitive to red and blue light to compensate for this absence.

The brain creates purple as a creative visual solution, even if it is not found in the colors of the basic visual spectrum.
