<P> ROYGBIV or Roy G. Biv is an acronym for the sequence of hues commonly described as making up a rainbow: red, orange, yellow, green, blue, indigo and violet . </P> <P> A rainbow spans a continuous spectrum of colors; the distinct bands are an artifact of human color vision . In ROYGBIV, the colors are arranged in the order of decreasing wavelengths: red is about 650 nm and violet about 400 nm . The acronym is memorable because Roy is a male given name, so Roy G. Biv sounds like a first name, middle initial, and a last name . </P> <P> In Classical Antiquity, Aristotle claimed there was a 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 . 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 to match the number of musical notes in the major scale . </P>
