During dark adaptation, photopigments are gradually regenerated as the sensitivity of the photoreceptors increases. This allows for better detection of dim light. Rhodopsin is not rapidly broken down, but rather is regenerated during this process. The cones for grey vision are not specifically stimulated more than the cones for color vision during dark adaptation.
