The tiny ice and water droplet sizes cause sunlight to be diffracted—it is obstructed by the droplets, is bent, and spreads out into its spectral colors. In fact, you'll need to travel up to the world's farthest polar regions and visit the Arctic (or Antarctica in the Southern Hemisphere). Arcs will be located far below the Sun or Moon (whereas cloud iridescence can be found anywhere in the sky), and its colors will be arranged in a horizontal band with red on top (in iridescence, the colors are more random in sequence and shape).
