In autumn many leaves are red and yellow with their waste substances. But where is the green colour from spring and summer? The green colour is “chlorophyll” (that’s not a Cornish word – it’s from Greek words for pale green and a leaf). In autumn it is broken down and it disappears. Remnants of green mixed with red make light and dark brown colours. Red leaves reflect red light and absorb other colours of light. On the other hand, green leaves absorb red (and blue) light and reflect green light. There is not enough sunlight in winter, so the red and yellow and light brown and dark brown leaves fall to the ground. Soon the trees will sleep.
