Acorns turn from green to brown as they mature on the oak tree. This color change is primarily due to the development of tannins and other compounds in the acorn, which provide protection and contribute to the seed's readiness for germination. As the acorns ripen, the chlorophyll breaks down, leading to the loss of green pigmentation and the appearance of brown hues. This process signifies that the acorns are reaching the end of their growth cycle and are preparing to fall from the tree.
Acorns are light brown or beige on the tops and the bottom is dark brown.
