Oxidation The leaves are spread out again, this time in a cool, damp atmosphere, and the oxidation process continues. The color of a tea leaf is originally green, but as oxygen reacts with the cell tissues, it begins to turn a copper color. This is very similar to tree leaves turning from green to brown in the fall.
