How Do We Perceive Color?

We see color because light bounces off things and lands in our eyes, helping us tell them apart.

Imagine you have a box of crayons, each one is a color. When the sun shines on your drawing, it's like the crayons are saying, “Hey, look at me!” The light from the crayons goes into your eye, and your brain says, “Oh, that’s blue! That’s yellow!”

Light is like a group of tiny dancers. When they dance on something white, all the dancers go out, that’s why white looks bright. But if the thing is red, only the red dancers come out, and that’s how we see red.

Your eyes have special helpers called cells that catch those dancing lights. Some cells are good at catching red dancers, some like blue ones, and others enjoy green. When they catch the light, they send a message to your brain, which says, “I see red! I see blue!”

So when you look at a rainbow, it’s like all the crayons are dancing together, each color showing off in its own special way!
