Autumn Foliage Color. The Process of Leaf Color Change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from the trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
Although not fully understood, several factors affect when and how leaves change color and the hues they produce. These factors include: 1  Shortening of day length. 2  Cooling temperatures. 3  organic pigments in the leaf cells. 4  sunlight intensity. 5  moisture. 6  tree genetic traits. 7  site characteristics. 8  latitude.
