How do we see beautiful colours in Autumn and enjoy the fall?

Explanation

Chlorophyll gives green colour to plants. During winter, there is not enough light for photosynthesis. So they use food, which are stored in summer. As the green chlorophyll disappears or fades away, we begin to see yellow, orange and red colour. We cannot see them in summer, because they are covered by green chlorophyll. But in autumn or fall season glucose trapped in the leaves, after photosynthesis stops. Sunlight and cool nights of Autumn cause the leaves turn this glucose into a red colour. It is the combination of all these things, that make the beautiful colours, we enjoy in the fall.
