The pathways of human color perception

Abstract

Color perception can be able to distinguish between light waves of different frequencies. It is also known as color vision. It is known that humans have trichromatic vision so that they can enjoy the colorful world and receive external information. Although there are thousands of colors in nature, the visible range of humans is limited. Our eyes cannot see the colors produced by ultraviolet and infrared light. Most of the colors in the visible spectrum can be made up of three basic colors (red, green, and blue). When these three basic colors are mixed according to different proportions and intensities, they can produce different colors. Color perception has also been studied to some extent. It is known that color perception starts from pyramidal cells in the retina, then it passes through a complex visual network, and finally, it is transmitted to the visual cortex. Thus, humans can see a colorful world and feel the charm of nature. How do people perceive color? What causes color blindness, and how can medical experts effectively correct this visual deficiency? This research is going to summarize the color vision pathway from the retina to the visual cortex and discuss the causes of color blindness and the existing correction techniques.
