In general, the leaves are tender green in the spring, dark green in the summer, red in some trees in the fall, and yellow in the fall.
And according to some botanists, the color of the leaves is close to infinity, there are as many colors as there are in the world, there are as many colors as the leaves, but the leaves we usually come into contact with are mostly green, yellow, and red, because the pigments in the leaves are working.

How many colors do leaves have?
I really don't know if I don't check, and I was shocked when I checked it, and it turned out that the color of the leaves was close to infinity. There are several colors in the world, and there are several colors of leaves. It's just that the ones we usually come into contact with are probably green, yellow and red.
It is the pigment in the leaves that plays a role, and through the continuous change of the quantity and quality of pigments in the body, the color of the leaves is transformed.
What is the reason for the colorful foliage?
In the leaves of plants, there are many natural pigments such as chlorophyll, lutein, anthocyanins, and carotene. The color of the leaves is due to the different content and proportion of these pigments.
In spring and summer, the content of chlorophyll is larger, and the content of lutein and carotene is lower than that of chlorophyll, so their color cannot be revealed, and the leaves show the green color of chlorophyll. Because the synthesis of chlorophyll requires strong light and higher temperature, in autumn, as the temperature drops, the light becomes weaker, the chlorophyll synthesis is blocked, and the chlorophyll is unstable, and the light is easy to decompose, and the decomposed chlorophyll can not be replenished. Therefore, the proportion of chlorophyll in the leaves decreases, while lutein and carotene are relatively stable and not susceptible to external influences.
As a result, the leaves show the yellow or red color of these pigments. This is why the leaves turn yellow or red in autumn, and there are also trees that have rare pigments that can undergo chemical changes in special environments to form richer colors.

The most common are green, red, yellow, and many more colorful! Winter is mostly white.

There are up to 6 colors of leaves. Green, cyan, yellow, purple, blue, red. The most common colors of leaves are green and cyan, and yellow is also a common color of leaves, but they all turn yellow in autumn when everything is ripe.
Other plants are rare colors, purple, blue, red.
In fact, green and cyan leaves are the most common, and they are also the common colors of all leaves in nature. But even the green and cyan leaves give different visual effects. Because even if it is green, it is divided into tender green, emerald green, and dark green.
For example, the leaves of the willow tree are tender green, and the leaves of the orchid are dark green, and they give people a different feeling.
Although the color of the leaves is not as complex as that of flowers, the color of the leaves is determined by the pigments inside the leaves. Many leaves, in autumn, the pigment changes, and the leaves turn yellow, such as plane trees, ginkgo trees, and willow trees.
There are also some leaves, which are originally red.

1. Green: The most common leaf color. 2. Golden yellow:
The chlorophyll in the leaves is destroyed and the lutein increases, turning the leaves yellow. 3. Red: The accumulation of anthocyanins and sugars in the leaves makes the leaves turn into different shades of red.
4. Purple: The accumulation of anthocyanins makes the leaves appear purple.
1. Green
The most common leaf color is green, in spring the trees have just sprouted, the tender green leaves have just grown, soft and lovely, in summer the trees grow luxuriantly, the leaves change from tender green to dark green, dark green, etc., some trees have green leaves all year round, such as pine, evergreen, etc.
2. Golden yellow:
The leaves of trees contain a lot of chlorophyll, these colors overshadow lutein, anthocyanins and other components with other colors, and when autumn comes, the temperature drops, the sunshine time becomes shorter, the chlorophyll in the leaves slowly decreases, and lutein gradually emerges, such as the leaves of ginkgo biloba, laurel trees, etc.
3. Red
Growing in the fragrant mountains, the leaves are like the palm of the maple, etc., because the leaves in the anthocyanins are more, after the chlorophyll is destroyed, the leaves become bright red because of the anthocyanins, and after the frost, the sugar stored in the leaves becomes more, which will also promote the leaves to turn red, according to the anthocyanins and sugar stocks, the leaves also have bright red, crimson, purple red and other colors.
4. Purple
Anthocyanins in leaves will increase due to the influence of low temperature, phosphorus deficiency and other factors, a large number of anthocyanins absorb blue light, green light, reflecting purple, thus causing the leaves to be purple, and anthocyanins are a natural pigment that is soluble in water in nature, and most of the colorful leaves are inseparable from it.
