In sharply defined rainbows, a set of narrow coloured bands can often be found repeating on the inside of the primary bow. Called supernumerary bows, they add an extra-special dimension to the display and are produced by diffraction as light waves cross each other exiting the raindrops, as seen here over Amsterdam, Netherlands.
