Application of the Single-hue Naming Method to the Determination of Elemental Hues

Elemental (unique) hues are those which cannot be perceptually analyzed into more basic hue components, and thus cannot be further described by other hue names. The most popular method for investigating the appearance of elemental hues is the method of Stemheim and Boynton (1966). In this method observers are given a set of hue terms with which to describe spectral lights. If a hue term is both necessary and sufficient to describe a stimulus, the hue is determined to be elemental.
