Quizplus · Accepted Answer

At night or in low light conditions, the cones, which are responsible for color vision, are not very active. Instead, the rods, which are responsible for black and white vision, become more active. This is why it is difficult to distinguish between colors at night because our visual system is relying more on the rods than the cones.
