Ginkgo biloba leaves have just grown in spring, and their leaves are light green. Summer gradually turns dark green, autumn gradually turns light yellow, then golden yellow, and in winter, the leaves slowly fall.

Extended data:

Generally speaking, the leaves of green plants contain chlorophyll, carotenoids and so on. In the growing seasons such as spring and summer, chlorophyll is always dominant, covering up other pigments. In autumn, as the temperature drops, the green leaves gradually decompose, carotenoids prevail, and the leaves are yellow.
