What color are the leaves?

The colors of leaves are red, yellow, green and so on. The color of leaves changes with the seasons.

The color change of leaves is inextricably linked with meteorological conditions.

1. The green color of leaves comes from chlorophyll, which contains a lot of chlorophyll, in addition to lutein, anthocyanin, sugar and other pigments and nutrients. After summer, the days get shorter, the temperature drops, and plants have passed the peak of the year. Chlorophyll production in leaves decreases and is destroyed as the weather gets colder. Ginkgo biloba, Populus alba, Cinnamomum cassia and other leaves lack chlorophyll, leaving only lutein, and the leaves turn yellow.

2. In the hilly forest of Xiangshan Mountain, there are dense cotinus coggygria trees with leaves like small round fans, and a large number of five-fingered maple trees, cypress trees, lacquer trees and Chinese toon trees. In late autumn, the weather is getting colder every day. In this suitable weather condition, anthocyanins in leaves will be exposed, making red very bright.

3. Especially before and after the first frost solar term, the chlorophyll on the leaves of frost-damaged plants is further destroyed, and the sugar stored in the branches and leaves will also increase, making the leaves more and more red. According to the amount of anthocyanin and sugar, leaves can form different colors such as bright red, scarlet, scarlet and purple.
