Why do clouds appear white?

Clouds appear white because tiny water droplets or ice crystals scatter all the colors of light equally.

Imagine you're playing with a big handful of tiny white marbles, that’s like what happens inside a cloud! When sunlight, which has many different colors, hits these tiny drops, it bounces around in every direction. Since all the colors are scattered the same way, they mix together and make white light.

If you look at something far away, like a big pile of white marbles from across the room, it might look gray or even blue if it's really far and you're looking through a lot of air. That’s similar to why the sky looks blue sometimes. But clouds are close enough, and the tiny drops are so small and numerous that they scatter all the colors equally, making them appear white.

So next time you see a cloud, think about those little marbles bouncing around, and remember, it's not magic, just light having fun!
