You see sunlight that has passed through a spherical drop of water diffracting the light into all the colors of the rainbow. When you see a red arch (for example) you don't see the other colors from those drops in the arch because they shine elsewhere. What you see is your very own personal view of the rainbow because you are standing where the arch shines only red light on you. Someone standing perhaps half a mile from you will see different colors from the water drops you are watching. The red (etc.) forms an arch because all the drops in the arch are at the correct angle relative to you and the sun to transmit only red to you. The water drops in the blue arch form a different angle relative to you and the sun. Actually there are two different paths for sunlight to travel through each water drop and you can sometimes see two distinct rainbows, if the angle is right.

White light bends in raindrops thus causing it to split into the colours of the rainbow and "bending".
