the regular and beautiful order and arrangement of color

The title of Moses Harris's book on color, originally published in 1766, is a story in itself:

The Natural System of Colours , Wherein Is Displayed the Regular and Beautiful Order and Arrangement, Arising from the Three Primitives, Red, Blue, and Yellow, the Manner in Which Each Colour Is Formed, and its Composition, the Dependance They Have on Each Other, and by Their Harmonious Connections Are Produced the Teints, or Colours, of Every Object in the Creation, and Those Teints, tho' So Numerous as 660, Are All Comprised in Thirty Three Terms, Only.
