Why are clouds usually black before rain?

At the beginning of the rain, one of the signs of recognition is that when we look at the sky, we will be cloudy with a dark gray color. Why is the color cloud so?

It is the thickness or height of the cloud that causes the cloud to be gray. When the clouds are thin, they will allow most of the light to pass through and be white. But like other light-transmitting objects, clouds will follow the thicker rule as less light can pass through.

First of all, we need to learn about the nature of clouds. Clouds are a collection of many tiny droplets of water or ice crystals, formed when steam condenses in pockets of rising air. Under normal weather conditions, the air continues to be pushed up, making the cloud more accreted.

These tiny particles of water and tiny ice crystals are small enough to disperse all colors of light. When light is made up of all colors, it will be perceived by our eyes as white.

When the clouds are thin, they will allow most of the light to pass through and the clouds will be white. When the thickness of the cloud rises, the bottom of the cloud will be darker due to less light penetrating, but can still disperse all colors. In the naked eye we will see that the cloud is gray and if we notice, we will see that the flat bottom of the cloud is always darker than the side.
