The primary color of bananas is yellow when they are ripe. Initially, bananas are green, and as they mature, they develop a yellow pigmentation due to the breakdown of chlorophyll and the increase of carotenoids. The yellow color is often associated with sweetness and ripeness, making bananas appealing to consumers. Some banana varieties can also be red or purple when ripe, but the most commonly consumed bananas, especially in North America, are the Cavendish variety, which are bright yellow when fully ripe. Bananas are not only a popular snack but also a vital source of nutrients like potassium and vitamin C.
