At night, the cones (responsible for color vision) do not function well under dim conditions, leaving us primarily reliant on the rods (responsible for black and white vision). Rods are less sensitive to color and are more useful under low light conditions, but they do not distinguish between colors as effectively as cones. Therefore, it is difficult to distinguish between colors at night.
