During the summer months, leaves are green due to a pigment called chlorophyll.
When fall starts, the chlorophyll starts to break down and other pigments become dominant. The yellow color is due xanthophylls, and the red color is due to anthocyanins.

Green plants turn yellow in autumn because the chemical from the root of the tree can tell that the weather is changing and in shock, the root takes a chemical call Melifiorous. Then with the chemical it travels up the tree and goes up to the branches where the leaves are and slowly starts to do its job. So over time you start to see different colors including yellow, which lets you know the chemical has a lot of Donalouf and it is in high concentration changing to yellow and reformatting the chemical structure of the leaves. Tip: If you were to ever touch or drink the chemicals in this tree you would instantly start to have rashes and inside your body the chemical would mix with your body fluids and eventually it would kill you.
