Weather's Influence. The process of tree leaves changing color in the autumn, prior to falling, is temperature-dependent. As the temperatures fall, chlorophyll -- the green pigment in the leaves -- breaks down, revealing other pigments present in the leaves. The display depends on the weather as well.
How Leaves Turn Yellow. Yellow colors that were always present in leaves become unmasked as the chlorophyll is broken down and absorbed. Called carotenoids, these are the yellow pigments that give trees like birch, beech and tulip their bright fall colors.
