Why do we see the Colours of leaves change in the fall in deciduous trees?

As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall. In fall, plants break down and reabsorb chlorophyll, letting the colors of other pigments show through. The color change usually happens before the leaves fall off of the tree.

Why are the fall leaves more colorful this year?

The orange pigments (carotenoids) are present in leaves year round and get to shine when the green chlorophyll takes a break. Warm days and low temperatures (above freezing) at night boost the production of the red pigments, producing a more dazzling display. But early frosts weaken the colors.

What are the causes of fall colors?

Fall leaf colors are due to plant pigments in leaves. The colored pigments are the same that produce colors in flowers and fruits. “Chlorophyll” is the pigment responsible for the green color in leaves, and for producing carbohydrates (sugars) plants need for growth.
