Leaves and Color
Leaves change color in fall because trees produce less chlorophyll, the green pigment that helps them make food from sunlight. As chlorophyll fades, other pigments become easier to see. Carotenoids can create yellow and orange tones, while some trees also develop red or purple colors from compounds called anthocyanins. Weather affects the display too: bright sunny days and cool nights often help produce stronger color.
Not every tree turns the same shade, and some leaves simply drop with only a brief color change. That variety is part of what makes autumn scenery so memorable.

Fall is marked by shorter daylight hours and cooler temperatures as Earth’s tilt changes how much sunlight each hemisphere receives. In the Northern Hemisphere, autumn begins around the September equinox, when day and night are nearly equal in length. After that, daylight steadily decreases until winter. The season is also known for harvest time, migrating birds, and the return of sweaters and hot drinks. Many places associate fall with pumpkins, apple picking, bonfires, and changing forests, which makes it one of the most recognizable seasons of the year.
