What color are the maple leaves?

Common colors of maple leaves are: green, yellow and red.

The color of maple leaves changes with the seasons. In spring and summer, maple leaves are green, and the chlorophyll content in leaves is much richer than other pigments, so leaves are green with chlorophyll, and the colors of other pigments are invisible.

Autumn is coming, and the maple leaves begin to fall. Before the leaves fall, trees no longer produce a lot of chlorophyll as in spring and summer, and existing pigments, such as chlorophyll, will gradually decompose. In this way, with the gradual reduction of chlorophyll content, the colors of other pigments will gradually appear on the leaves, so the leaves will show yellow, red and other colors.

Chlorophyll in maple leaves is gradually decomposed due to the temperature drop, and the faces of other pigments are exposed. Sugar stored in maple leaves will be decomposed into anthocyanins, making the leaves brighter.

Maple leaf is the leaf of a maple tree, which is generally palmately divided, about 13 cm long, slightly wider than the palm of an ordinary person. The largest three lobes have several prominent teeth, the base is heart-shaped, the leaves are rough, the upper part is medium green to dark green, the lower veins are hairy, and they turn yellow to orange or red in autumn. But a few areas are dark green.

Generally, it is palmately divided (some varieties are divided into three or seven points), with a length of 13 cm and a width slightly larger than the length. The three largest lobes have some protruding teeth and the base is heart-shaped. Spring and summer are green, and in autumn, maple leaves are orange or red due to the decrease of chlorophyll and the increase of carotenoids.
