Answer:

The chlorophyll (gives a leaf its green colour) breaks down, the green colour disappears and the yellow to orange colours become visible and give leaves part of their fall splender. At some time other chemical changes may occur, which form additional colours through the development of red anthocyanin pigments.

Yellow to orange pigments, carotenes and xanthophyll pigments. In the fall because of changes in length of daylight and change in temperature, leaves stop their food-making process, chlorophyll breaks down, green colour disappears and the yellow-orange colour is more visible.

All the colours are visible, mixing of varying amounts of the chlorophyll residue and other pigments in the leaf during the fall season

Weather affects the colour intensity; temperature, light and water supply have an influence on the degree of fall colour.

Low temperatures above freezing, favour anthocyanin formation of bright red.

Early frosts, weaken the brilliant red colour.
