Why Do Leaves Change Colour?

The video explains how leaves change color due to different pigments: chlorophyll, carotene, and anthocyanins. Chlorophyll, responsible for green color, is unstable and breaks down in sunlight, requiring constant renewal. In autumn, chlorophyll production stops, revealing carotene, which gives leaves an orange-yellow hue. Anthocyanins, formed from sugars and proteins, can make leaves appear red. The dominant pigment determines the leaf color, which varies by tree and season.
