Deciduous trees have unique autumn leaf colors that are specific to every species. Fall's most common leaf colors are red, yellow, and orange.

Of course, autumn happens around the globe, and brilliant leaf displays are not just an American treat. Imagine floating down a winding river and enjoying brilliant autumn colors for the journey.

Leaves also contain carotenoids, which produce yellow, orange and brown colors. In the autumn, they begin to produce more anthocyanin , which gives them red and purple hues.

But in autumn as "leaf-peepers" from around the world descend on the region's rolling hills and fetching small towns to witness its kaleidoscopic foliage, that all changes.
