Influence of Red and Blue Pre-Adaptation on Hue Matching of Purple Samples

Abstract

This experiment was designed to show the effect, if any, of chromatic adaptation on hue matching of purple painted samples of different saturations. Five experienced observers were adapted for 1 min to a red field, then asked to find the hue match for each of three test samples from among a set of samples representing the complete hue circuit in 100 steps at middle saturation. The three test samples were of slightly greater saturation and representative of a range of purple samples. The entire procedure was repeated with blue and neutral pre-adapting fields, all under source C illumination. Results indicated that pre-adaptation did influence the hue-match selections, the average red–blue adaptive shift being about one Munsell hue step. Observers made systematically different hue matches for the same test sample, in accordance with their ages. A method for determining graphically the state of adaptation at the time when the hue judgments were made showed that the chromaticity of the test samples was at least as influential as either the neutral surround used or the pre-adaptation stimuli.
