What color are the leaves in spring, summer, autumn and winter?

There are different seasons in the north and south. Seen from the north, there are no leaves in spring. With the increase of temperature, they germinate slowly, green in summer, yellow and red in autumn, and no leaves in winter. The leaves in the south are basically green, and will fade in spring and winter. This is well known and obvious. Living in different places has different feelings. The north is dry, the weather is cold and the south is humid, and the climate is different.
