Colours Of Leaf

Chlorophyll is responsible for the green colour of leaves (see Shedding light on Photosynthesis), but in autumn, some forests or crops lose their green colour and turned spectacularly coloured. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from the trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.

Under optimal conditions this process of chlorophyll loss is very orderly and allows the plants to resorb much of the nitrogen in the structure of the pigment.
