színérzékelés
Színérzékelés refers to the ability of an organism to perceive and interpret differences in the wavelengths of light, which we commonly experience as color. This process involves specialized photoreceptor cells in the eye, primarily cones, which are sensitive to different ranges of wavelengths. Humans typically possess three types of cone cells, each most sensitive to red, green, or blue light, a system known as trichromatic vision. When light enters the eye, it stimulates these cones to varying degrees, and the brain then processes these signals to create the perception of a specific color.
The interaction and relative stimulation of these cone types allow us to see a vast spectrum of
Color blindness, or color vision deficiency, occurs when one or more types of cone cells are absent,
