Niagara Falls has been nicknamed the “Rainbow City”. On any given sunny day, a rainbow can be seen over the falls, adding to the charm of the city. People from around the country travel to see the falls, but unless they are also viewed at night, one cannot fully comprehend their true beauty. Each night, various-colored lights illuminate the falls. Blue, yellow, purple, green, and pink light up the falls, creating a flowing rainbow of water for all to see. The lights change every few minutes fading in and out, softening the effect of the water.
