Blurtphoto Roy G. Biv #roygbiv #colorchallenge

Welcome to the #blurtphoto #colorchallenge

Sometimes known as #roygbiv here on Blurt.

This photography / art challenge goes all the way back to the glory days of Steemit.com circa 2017 … but the origins of ROYGBIV are much more ancient … back to the days of Aristotle.

The Greek philosopher Aristotle (384-322 B.C.) made significant and lasting contributions to nearly every aspect of human knowledge, from logic to biology to ethics and aesthetics.

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.

It goes like this : ROYGBIV…

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, Sir Isaac Newton divided his color circle, which he constructed to explain additive color mixing, into seven colors.

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. Illustration from Newton's Opticks, Fourth Edition, 1730.

Sir Isaac Newton's observation of prismatic colors. Comparing this to a color image of the visible light spectrum shows that Newton's "indigo" corresponds to dark blue, while Newton's "blue" corresponds to cyan. For more on this, see Indigo.
