Our Honored Guest, Mr. Roy G. Biv

Rainbow over Kokkylia, Kefalonia

 Few natural phenomena are as universally admired as rainbows.

Those unbelievable arches of color-tinted light, filling up the sky after a rainfall, are the material legends and fairy tales are made of.

Hope, optimism, good tidings, and luck are just some of the words frequently attached to any description of rainbows.

Of course, the prerequisite conditions for the formation of rainbows are better left to be explained by those more scientifically inclined than yours truly. (Something to do with the interaction of light, raindrops and sun rays, but physics was never my strong suit).

There are seven spectacular colors distinctly visible to the human eye, and they appear in a specific order (reversed on the top rainbow, if there are two).

Remembering the order of the colors is easy thanks to an ingenious mnemonic device. All you have to do is remember the name of a most respectable gentleman: Roy G. Biv. 
(RedOrangeYellow Green BlueIndigoViolet).

Rumor has it that his permanent residence is ...over the rainbow. Though he is of undeclared profession, I'd say that he is eternally committed to carrying that pot of gold from one side of his residence to the other with such speed as to confuse the seekers and, thus, perpetuate the search!
