Darkness, in contrast with brightness, is a relative absence of visible light. It is the appearance of black in a color space. When light is not present, rod and cone cells within the eye are not stimulated. This lack of stimulation means photoreceptor cells are unable to distinguish color frequency and wavelength. The resulting perception is achromatic and in the case of darkness, black. The emotional reaction to darkness has metaphorical importance in many cultures.
