Chemical breakdown of chlorophyll
(not much different from your own breakdown of hemoglobin)
The most vibrant colors of autumn leaves in nature are typically red, orange, and yellow.
This change in color in leaves during autumn is due to the destruction of chlorophyll, the pigment responsible for the green color in leaves. As the chlorophyll breaks down, other pigments such as carotenoids (orange) and anthocyanins (red) become more visible.
During the autumn season, fall leaves change color to shades of red, orange, yellow, and brown.

Deciduous forests, particularly in the fall season, are known for having orange, red, and yellow leaves. These colors come from pigments in the leaves that are revealed as the green chlorophyll fades during the autumn months.
* The Quaking Aspen of North America is known for its leaves turning spectacular tints of red and yellow in the autumn of the year (and usually in the early autumn at the altitudes where it lives). * It is like a shade of orange, such as autumn leaves. * There's also an aspen silver.
Autumn leaves change color because the green on the leaves in the summer is actually chlorophyll (not sure if it is spelled right). When it is autumn or winter the chlorophyll is blown off and reveal the real colors(Red, Orange, etc).
When a banana begins to ripen, the peel begins to change color. It changes from green to yellow to brown. The same occurs with autumn leaves. The green leaves change from green to red and yellow and orange and eventually brown.
Leaves that turn red or yellow in autumn have lost chlorophyll, the green pigment responsible for photosynthesis. As chlorophyll breaks down, other pigments such as carotenoids (which produce yellow and orange colors) and anthocyanins (which create red hues) become more visible. This change is triggered by shorter daylight hours and cooler temperatures, signaling the trees to prepare for winter.
autumn leaves
During the autumn season, tree leaves can change to various colors such as red, orange, yellow, and brown. This change in color is due to the breakdown of chlorophyll, the green pigment in leaves, revealing other pigments like carotenoids and anthocyanins.
