Clouds are White because they reflect light from the Sun?

[Bretrick]

They’re made of water drops or ice crystals. So they reflect the light?

What about the Dark Clouds om the Horizon?

Maybe the water droplets are covered with dirt and grime?

Possibly

Learned something new. Thanks for that.

Here’s a bit more complicated answer than in most articles. Water is clear in a glass, so why are clouds white?

And that’s why clouds are white. Each drop, or at least each several drops, are essentially a step of a random walk for the incoming light waves[2]. If the cloud is very large compared to the size of the step (which is on the order of a few times the distance between drops), then the light is much more likely to wander back out to the same side of the cloud it came in than it is to wander all the way to the other side.

Thank you for sharing this information.
As the article says, “Sometimes there’s a lot of insight to be gained by asking kid-style questions, even if the path to the answer is kind of random.”

Thanks for that butterscotch, I had a sort of inkling that it was something to do with passage of light through different materials. Different coloured clouds can be the result of fine particles picked up when the moisture is lifted into the atmosphere on the rising warm air. A good example of this is when we sometimes get sand from the Sahara being deposited on vehicles here in England after the rain.
