The colorist, designed to correct the commonly held theory that red, yellow, and blue are the primary colors, and to supply the much needed easy method of determining color harmony; together with a system of color nomenclature and other practical information for artists and workers or designers in colors
The Colorist is a 1908 New York colour manual by J. A. H. Hatt, published by Van Nostrand for artists and designers, and it sets out a colour wheel system with a cut-out mask for judging harmony. Its plates are plain line charts: a harmony wheel with a central mask, a nomenclature ring of named hues in fifteen-degree steps, and paper masks to cut out, offering a clear model for designers building colour wheels and schemes.
