What is color perception?

Color perception is a fascinating number of physical and chemical reactions that allow some organisms to see color. The process of color perception is literally everything in the mind, with an eye containing a device that reacts to light so that the brain can process it. The number of colors that the body can distinguish may vary significantly, from animals that can see a very wide range of millions of colors to animals that see to a much more limited range.

Two types of cells are responsible for vision: bars and cones. Both cells are located in the retina and respond to the light when entering the eye. The rods are very sensitive to light, allowing vision in a variety of light levels, while the cones are sensitized to the colors of specific wavelength range. People have three different types of cones sensitized to short, medium and long wavelengths and are particularly sensitive to yellow and green light. Organisms with three types of cones are known as Trichromatic and other animals can have two types of cones (dichromatic),while others have up to five (pentachromatic).

By 2005, scientists assumed that the number of cones in the eye was about the same for all people and that all people had the same number of different types of cones. However, when the imaging technology was developed that could be used to explore the living eye and distinguish between the different types of cones present, scientists have learned that people actually have very irregular cones distributions. 40% of one person's cones can be sensitive to moderate wavelength, while someone else could only have half of this number, but both people would perceive color in the same way, suggesting that the key aspects of color perception in the brain, not the eye.

6ength are sensitized. The reaction is sent along the optical nerve to the brain and the brain processes information, allowing the body to see color. Color perception is important for many animals as it can be afterUsed to distinguish more natural environment and because colors are often used as allusions. For example, poisonous mushrooms are sometimes clearly colored as a warning.

The process of visual perception occurs so fast that people feel as if it were immediate when they look at something and see it immediately. Eyes are also constantly returning new information, allowing people to detect changes such as movement. Although the basic mechanics of how vision and colors are understood, the processes for scientists are still a little mysterious. For example, the mechanisms of color blindness are not fully understood.
