How Planets Get Their Colours?

Planets get their colours based on what they're made of and how light interacts with them.

Imagine you have a box full of different kinds of crayons, red, blue, green, yellow. Each planet is like one of those crayons, but instead of paper, it's space! The colour we see depends on the materials that make up the planet’s surface or atmosphere.

Think about how your skin looks in the sun, sometimes it turns red or tan. That happens because of something called light absorption. Some planets are covered with iron oxide, which is like rust, and that makes them look red, just like when you leave an iron nail outside in the rain.

The Earth’s oceans look blue from space, right? That's because water reflects blue light more than other colours. Some planets have thick atmospheres filled with gases that act like a giant filter, they absorb some light and let others through, which makes the planet appear in different colours, just like how sunglasses can change how things look!
