Why all objects appear in the shades of grey and black in dim light

We can see objects and colour when light from an object is reflected back to our eyes and processed by the brain.
E.g. We can see the wall in a room only because the light from a bulb reflects from it's surface and enters our eyes.
When there is no light or the lights are dim, this reaction does not take place properly. Our eyes do not get the appropriate signals and our brain cannot process this incomplete information, so objects only seem grey and black instead of real colours

Answer:
Explanation:
The retina of our eyes contains two types of photoreceptors – rods and cones. The cones detect colour. The rods only let us see things in black, white and grey. Our cones only work when the light is bright enough, but not when light is very dim. This is why things look grey and we cannot see colours at night when the light is dim.
