Autumn leaf color is a phenomenon that affects the normally green leaves of many deciduous trees and shrubs by which they take on, during a few weeks in the autumn season, one or many colors that range from red to yellow. The phenomenon is commonly called fall colors and autumn colors, while the expression fall foliage usually connotes the viewing of a tree or forest whose leaves have undergone the change. In some areas of Canada and the United States, "leaf peeping" tourism is a major contribution to economic activity. This tourist activity occurs between the beginning of color changes and the onset of leaf fall.

Famous quotes containing the words autumn, leaf and/or color:
“They may bring their fattest cattle and richest fruits to the fair, but they are all eclipsed by the show of men.

—Henry David Thoreau (1817–1862)
“I believe a leaf of grass is no less than the journey-work of the stars.”
—Walt Whitman (1819–1892)
“Good Hamlet, cast thy nighted color off.”
—William Shakespeare (1564–1616)
