When we looking at the sky, we often see the white clouds – its like the color of cotton. Nothing special on this color. However, have you ever thought of it, how do clouds that contain colorless water look white like cotton?

The color does not just happen. White in the clouds during the day comes from the original color of sunlight.

When passing through clouds, sunlight will interact with water vapor. The sun’s rays are scattered by far greater droplets of water.

That is, the collection of water vapor stores all colors. When all colors are put together, that means they will keep them white like the original sunlight.

Sometimes it’s gray

When cloudy, the clouds turn gray. This is actually a matter of perspective.

The color of clouds is produced by sunlight that interacts with water vapor. When interacting, the light is then reflected back to the top or side of the cloud.

That makes the top or sides of the cloud usually whiter.

But in the case of heavy clouds, clouds store more water vapor which will be reduced to rain. This causes more light to spread.

That way, there will be less sunlight reaching the lower cloud. As a result, we tend to see clouds becoming gray.

In fact, when viewed at the top of the cloud remains white. We can prove this when flying in a plane that crosses over the clouds.
