Why does a ripe banana appear yellow?

• The light diffracts as it passes around the edges of the banana, causing its surface to appear yellow.

• The yellow light is stronger than any other light, causing the human eye to see the banana as yellow.

• The yellow light is reflected toward the eye while all other colors of light are absorbed by the banana.

• All other colors of light are reflected from the banana’s surface, but the yellow light stays in the banana.
