Evergreens are green. There are also yellow, red, silvery, etc... However, in general, the yellowing of leaves in autumn is due to the fact that there are three main pigments in the mesophyll cells of plants:

Chlorophyll, lutein, and carotene, the synthesis of these three pigments is related to temperature. When the temperature drops in autumn, the secretion of carotene increases, and carotene is orange, so the leaves turn yellow or red.

Autumn temperatures drop gradually, but generally slower than winter. Due to the difference in wet and dry conditions, different regions will have cold and rainy weather conditions, or dry and cool weather conditions. In the colder late autumn, due to the large temperature difference between day and night, the water vapor transpired during the day will condense at night, either as dew or as frost.
