Why do leaves change color?
Quick Answer
Leaves change color because trees stop making as much green chlorophyll when days get shorter and cooler. As the green fades, other pigments—yellow, orange, and sometimes red—become visible.

Story Synopsis
In autumn, trees put on a color show. This story explains why leaves change. Miluna shares that chlorophyll is the green pigment that helps leaves use sunlight to make food. When days get shorter, trees prepare for winter. They make less chlorophyll, so the green fades. Other pigments that were there all along—like yellows and oranges—start to show. Some trees also make red pigments. The tone stays cozy and seasonal, inviting children to notice nature’s cycles. Curiosity stories like this make the world feel orderly and soothing.
Story Excerpt
Have you ever noticed that some trees stay green all year, while other trees have leaves that turn beautiful colors in the fall? During spring and summer, leaves are green because they are full of something called chlorophyll. Chlorophyll is what helps leaves catch sunlight and turn it into food for the tree. It's like the leaf's kitchen, always busy making food. And chlorophyll is bright green, so that's the color we see. But when fall comes and the days get shorter and cooler, something changes.

In One Glance
Leaves contain chlorophyll, the green pigment used for photosynthesis. In fall, shorter days and cooler temperatures signal many trees to slow photosynthesis and break down chlorophyll. As green fades, pigments like carotenoids (yellow/orange) become visible. Some trees produce anthocyanins, creating reds and purples. This helps the tree prepare for winter dormancy. The story frames color change as a calm seasonal pattern.
