Leaves are not all green, but most of the things we see in our life are green. In nature, the colors of leaves are still colorful and various. The color of the leaves is determined by the sun light and the absorption of the leaves. There are seven colors in the sun light, but six of them can be absorbed by the leaves except for the green. Only the green is absorbed less and reflected a lot. Because the leaves rely on the body's green leaves to absorb sunlight, synthetic nutrients to provide growth, chlorophyll is green, so the whole leaves are green.
1. Red: there are many red leaves, such as Japanese red maple. The color of the newly grown leaves is bright red. As they grow, they will turn red brown, and maple and hemp stalks 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, because of the decrease of chlorophyll, they naturally turn yellow.
3. Purplish red: there is another color darker than red, for example, red Phoebe is purplish red.
