What you may be asking is why do objects illuminated by moonlight appear to humans as lacking color? Now the answer to that lies in the detection of light in the eye. Is it Rods or Cones which respond to low light levels?

Answer 2

For information on the rods and cones, here are some sources:

I hope this helps a little more. Thanks for asking.
