If you want to know why leaves change color, according to the USDA Forest Service: Here it is in a nutshell: The brighter the sunlight in the fall, the greater the production of anthocyanins and the more brilliant the resulting color display that we see. When the days of autumn are bright and cool, and the nights are chilly but not freezing, the brightest colorations usually develop. Adequate rainfall also keeps the leaves on the trees longer and enhances the color. [ info ]
