A sunset looks colorful because light travels through more air and changes colors as it goes.
Light is like a group of tiny colored balls that come from the sun. During the day, these balls travel straight to your eyes, so you mostly see white light, which is all the colors mixed together.
But when the sun is low in the sky at sunset, those colored balls have to go through more air, like swimming through a big pool of water. This makes the blue and purple balls get scattered away, leaving the red, orange, and yellow balls to reach your eyes. That’s why you see bright reds and oranges in the sky.
Why It Feels Like a Painting
Imagine you’re eating a bowl of cereal. The milk is like the air, it goes through the cereal (which is like the sunlight), and some pieces get soaked up more than others. In the same way, the air soaks up the blue light, letting the warm colors shine through.
Sometimes, if there are clouds or pollution in the air, it’s like adding extra flavors to your cereal, making the sunset look even more fun and vivid!
