Why do green apples appear green?

Chlorophyll is a green pigment that is found in all plants. It absorbs blue and red light from the sun and reflects green light, which is why plants look green. When apples are young, they are green because they contain a lot of chlorophyll. As they ripen, the chlorophyll breaks down and the apples turn red, yellow, or orange.

Some green apples, such as Granny Smith apples, stay green even when they are ripe. This is because they contain a higher amount of chlorophyll than other apples. Other green apples, such as Braeburn apples, turn green when they are exposed to sunlight. This is because the sunlight causes the chlorophyll to be produced.
