Explore the history and development of color order systems from the 17th century to modern times. Discover early systems by Forsius, Mayer, and Harris, leading to Munsell and Natural Color Systems. Dive into the structure of the Munsell system, NCS space, and Coloroid system. Learn about hue, chroma, values, and color spaces like CIELAB. This guide provides insights into the evolution of how colors are organized and understood.

COLOUR ORDER SYSTEMS and COLOUR ATLASSES
Early colour order systems • Sigfrid Aronus Forsius(1611) was probably the first to device a three-dimensional model of colour space in the form of a sphere, where he systematically organized colour samples with white and black at the poles and yellow and blue, red and green at opposite points on the equator.

Natural colour system -1 • Hering colour theory • six elementary colours: • two achromatic: white - black • four chromatic:yellow, red, blue, green • yellow - blue • red - green antagonistic colours
Natural colour system -3 • The hue circle of the NCS system • Opponent hues and hue descriptors
Natural colour system -4, and NCS atlas • NCS constant hue triangle • c = chromaticness • s = blackness • S SSCC: blackness chromaticness,e.g.: S 5010 - Y70R • No simple conversion between NCS notation and CIE tristimulus values

Further colour order systems • OSA - UCS system • samples on a cuboctahedron lattice • lightness and two opponent axes • DIN system (derived from Oswald system) • hue, saturation,darkness degree • Coloroid colour system • based on colour harmony
Coloroid colour system • Hue notation in Coloroid:A = 10 … 76 • Saturation: T • Value: V
