Why do leaves change color in the Fall?
Fall is known for its beautiful fall colors.
What causes leaves to turn yellow, red, purple, and orange? The simple answer is:
The reason is simple. Leaves experience changes in how they make food because there is less sunlight and the temperatures are cooler in fall.
Leaves begin to change color as chlorophyll, the substance that gives green leaves their color, begins to disappear.
Red anthocyanin pigments are responsible for some chemical changes, which can reveal reddish or purplish hues in trees like sumacs and dogwoods. Bright orange colors are displayed by sugar maples.
As some trees only display yellow colors, fall foliage can vary widely. Trees such as oak can often be found with brown coloring.
These colors are caused by the different amounts of chlorophyll residual and other leaf mixtures during the autumn season.
