Leaves look different colors because they have special color-makers inside them. During the summer, a green color-maker called chlorophyll is very strong, so leaves look green. But in autumn, this green maker fades away, and other hidden colors like yellow or red show up instead.
Examples
- A leaf turns yellow when the green color-maker fades away.
- A tree changes to red because it makes a new kind of color-maker in autumn.
- Some trees stay green all year round because their color-makers never fade.
