Hints of color are developing in the woods at The Morton Arboretum. Green and yellow are still the dominant colors, with oranges beginning to develop in the tops of the sugar maples. Once bright sunny days and cool nights arrive, the pigments in the leaves will shift and the colors will develop further.
