1、 Are they all green

The leaves are not all green, but most of them are green in life. In nature, the colors of leaves are still colorful and various. The color of the leaves is determined by the sunlight and the absorption of the leaves. There are seven colors in the sunlight, but all six except green can be absorbed by the leaves. Only green is absorbed less and a large number of them are reflected. Another reason is that the leaves absorb sunlight and synthesize nutrients to provide growth. The chlorophyll is green, so the leaves are green as a whole

2、 Other colors

1. Red: there are many red leaves. For example, the color of newly grown leaves of Japanese red maple is bright red, which will turn into reddish brown with growth, while red maple and yamama stalk are also red. Like Chinese red maple, it is green at first, and then it turns red in autumn

2. Yellow: the yellow ones are mainly Ginkgo biloba. In autumn, they naturally turn yellow because of the decrease of chlorophyll

3. Purplish red: another color is darker than red. For example, Heather is purplish red
