Question

explain how we see different colours of an object

Answer 1

by reflection of light and colour absorbing phenomenon.

Answer 2

Let me take a example as banana...

now, ☆When you look at a banana, the wavelengths of reflected light determine what color you see. The light waves reflect off the banana's peel and hit the light-sensitive retina at the back of your eye. That's where cones come in. Cones are one type of photoreceptor, the tiny cells in the retina that respond to light.☆
