Why Do We See Colors When It's Actually Light?

We see colors because our eyes catch different kinds of light. Think of it like a rainbow, the sun sends out all the colors mixed together, but when we look at something blue, only the blue part reaches our eyes. Our brain says, 'Oh, that’s blue!' and that’s how we know what color things are. It's like using filters to see just one piece of the whole light show.
