The proximity factor in colour-difference evaluations Sharpe, Lindsay Theodore
Abstract
The effect of diyiding [sic] line width (sample proximity) upon sensitivity to supra-threshold and threshold colour differences is explored by three methods involving ratio comparisons, liminal determinations, and repeated colour matchings. The results suggest, in general, that sample separation impairs lightness discrimination more than chromaticness discrimination and that it may by necessary to introduce a proximity factor into colour difference formulae when evaluating threshold or small-sized colour differences.
