White light is refracted through the drops of water which displays all the colours, but the human eye can only see one colour per drop, and that is why the height of the drops is a crucial determinant in the order of the colours which is always respected.

The highest drops to the outside allow us to see red, while the lowest drops inward allow us to see purple.
