Every autumn, green leaves transform into brilliant reds, oranges, and yellows — but the surprising truth is that some of those colors were hiding inside the leaf all along. The episode traces what happens step by step when days get shorter and trees stop making the green pigment chlorophyll, revealing hidden pigments and even building brand-new ones. It also follows the fallen leaves to the forest floor, where decomposers break them down into nutrients that feed the next generation of growth.
