A rainbow is not something that can be touched or studied or examined. A rainbow is an optical illusion. This means it is nothing more than a light ‘trick’. Because a rainbow is light, this also means that a rainbow is never in any one place. In fact, no two people see the exact same rainbow. Even if ten people are standing side by side and all say they see a rainbow, they are not seeing the same one. Because of the way the light bends, the red ribbon of color in a rainbow will always be on top on the outer edge of the rainbow. The blue will always be on the bottom or the last color on the inside edge of the rainbow.
A double rainbow happens when the light bends and reflects off the water drops in the air TWICE. In other words, the second rainbow is a reflection of the first rainbow. The second or double rainbow will be lighter in color and the colors will be reversed. When you see a double rainbow, you will notice that the sky between the two rainbows is dark, and unlit. This band of dark sky is called Alexander’s Band. It has this name because of the man who first noticed that there was no light in the sky between the two rainbows. His name was Alexander of Aphrodisias. He lived over 2,000 years ago. No matter how rainbows are made or which color is on top or bottom, we can all agree that rainbows are one of the prettiest sights in nature.

The reverse image by Canadian artist Tony Bianco combines detailed engraving, innovative colour technology and various finishing techniques to showcase a brilliantly coloured rainbow on a stormy day. Against the rolling hills in the background, a farmhouse and barn sit atop a gentle slope where a road leads to two round bales in the foreground. The eye is naturally drawn to the multi-coloured arc that descends from the dark storm clouds above; here, the skilful combination of diffused technology and vivid paint adds a subtle transparency quality to the rainbow’s radiant colours, and a faint glow above it, as the rain tapers off. There’s a hopeful clearing above this rural landscape, with the appearance of blue sky in the break between the clouds behind the rainbow.
