Shown above is a rousing double rainbow bracketing the Eiffel Tower as viewed from a window of my home in Paris, France. The pure colors of the primary bow (at center) are due to the large drop sizes of the showers that produced the bows. The secondary bow (at left) results from two internal reflections in a raindrop. It's only about 43 percent as bright as the primary bow since some light is lost each time a reflection occurs. Note that the Eiffel Tower itself appears within Alexander's Dark Band.
