Ketchikan, Alaska - Somewhere over the rainbow... might be a pot of gold. The idea that a pot of gold can be found at the rainbow's end originated somewhere in old Europe. In Silesia, an obscure area of eastern Europe, it was said that the angels put the gold there and that only an unclad man could obtain the prize. Hmm....

What makes rainbows so mysterious is this simple but often puzzling fact: Rainbows are light. You can't touch them. You can't reach around behind them. They exist only in the eyes and sometimes the photographs of the people who see them.

A rainbow is visible light broken into what we see as seven colors: red, orange, yellow, green, blue, indigo and violet. They always appear in the same order, with red on top and violet on the bottom, in a main rainbow. In a secondary rainbow, they appear in the opposite order.
