One can sense colours only in bright light. Can you explain why?

Explanation

i. The retina in our eyes is made of different cells viz., rod-shaped and cone-shaped.
ii. The rod shaped cells respond to intensity of hght and send the information to brain. While cone shaped cells send information of different colours of light to the brain.
iii. Rod like cells are sensitive to faint light, whereas, the comcal cells do not respond to faint light.
Hence, one can sense colours only in bright light.
