Give scientific reason:
One can sense colours only in bright light.
- The light sensitive screen of the eye, called the retina, has two types of light sensitive cells.
- Rod cells are concerned with vision in dim light and cone cells are responsible for the vision in presence of light.
- Cone cells are also concerned with colour perception. They do not respond to dim light or no light.
- Thus, the knowledge of the colour is possible in presence of light and not in dark.
- Hence, we can identify and differentiate colours in presence of light.
