We see colors because of the light around us. Light comes in different types, like red, blue, and green. Our eyes have special cells that can catch these types of light. When they do, our brain tells us what color we're seeing. For example, if you look at a rainbow, each color is made from a different kind of light.
Examples
- A red apple appears red because it reflects red light and absorbs other colors.
- When you mix blue and yellow paint together, you get green.
- The sky looks blue on a sunny day because the atmosphere scatters shorter wavelength light more effectively.
