The trichromatic theory suggests that color vision is based on the stimulation of three different types of cones in the eye, each sensitive to wavelengths of light that correspond to either red, green or blue. However, color blindness can occur when one or more of these types of cones is missing or not functioning properly. Additionally, afterimages occur when the visual system becomes fatigued, leading to a temporary shift in color perception, which cannot be explained by the trichromatic theory alone.
