What happens on the surface of a material

Hello friends,

Every object has certain color, because it reflects that potion of light & absorbs all other visible radiation,

What is the mechanism that happens on the surface of a body, which makes it reflect certain portion & absorb rest portion.

How much do you know about quantum mechanics and electron energy levels?

The basic idea: electrons in the material cannot react to all incoming light, just some frequency ("color") ranges. In those ranges, they can absorb and re-emit light, or absorb light and release the gained energy to the surrounding material.
That is not a perfect description, and not all processes follow that pattern, but it should give some idea what happens.

I have fair knowledge about electron energy level & quantum mechanics,

can you please guide me to understand this phenomenon.

Thank you.
