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.
Green: The green color of leaves throughout spring and summer comes from chlorophyll, a pigment vital to photosynthesis. Yellow and Orange: Along with chlorophyll, there are yellow and orange pigments, carotene and xanthophyll, inside some trees' leaves. For most of the year, these pigments are masked by chlorophyll, but as the chlorophyll breaks down and the green color dissipates, the yellow to orange colors become visible.
