ABSTRACT Colour appearance measurement aims to describe, both qualitatively and quantitatively, what a person experiences as colour. Unfortunately, current measurement techniques are fundamentally limited because they give observers a set of component hues - the hues they must use to describe all the colours they experience. This circular approach is also un• satisfactory based on individual variations in retinal photoreceptors. To circumvent these limitations, the technique of Partial Hue-Matching (PHM) was developed, which provides an unbiased estimation of the minimum set of component hues observers use to decompose their colour experiences. PHM does this by asking observers to match colours for common hues, and from this uncovering chromaticity classes: these common hues form the set of component hues. Crucially, PHM does not define to an observer what hue is, and does not suggest which hues should be considered component hues: rather, comparisons among colours reveal their relationships and lead to the establishment of chromaticity classes.
