It is known to all that clouds are usually white, while rain clouds are darker grey in colour, but why the rain clouds are darker grey ?
Let's know why,
First, let me tell you how the clouds are formed. When the air near the ground warms, it starts to rise, taking the water vapour along with it.
As it goes higher into sky, the starts cooling causing the water vapour condense onto the dust present in the atmosphere from the volcanoes, vehicle exhaust and other sources. This results in water vapour and ice water coalesce or join together to form the clouds.
The tiny particles of the clouds equally scatters all colurs of light, which together make up the white light. Thus, the clouds seems white to us.
However, the rain clouds are gray in colour instead of white due to their thickness or height.
This clouds gather more water vapour and ice particles in it, and gets thicker and denser than the normal clouds. The thicker it gets, the more light scatters through it which results in less light penetrating through it all the way.
Thus, the particles on the underside of the rain cloud don't have enough light to scatter to our eyes.
So the base of the cloud appears gray to us as we look on from the ground below.
