The conventional seven colours of the rainbow symbol
Natural rainbows typically do not show seven colours at all

Roy G. Biv is an acronym for the sequence of hues in a rainbow:

A rainbow spans a continuous spectrum of colors; the distinct bands are an artifact of human color vision. In Roy G. Biv, the colors are arranged in the order of decreasing wavelengths, with red being 650 nm and violet being about 400 nm. Other variations are ROYGBIV and VIBGYOR.

[edit] History

Newton's color wheel that introduced indigo as a basic color. The uneven color division along the color circle correlates with the intervals of the musical major scale.

In Classical Antiquity, Aristotle claimed there was a fundamental scale of seven basic colors. In the Renaissance, several artists tried to establish a new sequence of up to seven primary colors from which all other colors could be mixed. In line with this artistic tradition, Newton divided his color circle, which he constructed to explain additive color mixing, into seven colors.[1] His color sequence including the tertiary color indigo is kept alive today by the Roy G. Biv mnemonic. Originally he used only five colors, but later he added orange and indigo, in order to match the number of musical notes in the major scale.[2][3]

The Munsell color system, the first formal color notation system (1905), names only five "principal hues": red, yellow, green, blue, and purple (although note that Munsell's purple is not a spectral hue).[citation needed]

Another traditional mnemonic device has been to turn the initial letters of seven spectral colors into a sentence. In Britain the most common is "Richard Of York Gave Battle In Vain." The mnemonic is said to refer to the defeat and death of Richard, Duke of York at the Battle of Wakefield. In order to avoid reference to this defeat, people from Yorkshire developed the alternative "Rowntrees Of York Gave Best In Value." Alternatively, the biblically inspired "Read Out Your Good Book In Verse" may be used.
