“…It is remarkable that the order of likeness obtained by using this method is very similar to that obtained in Ref. 4 where the authors considered the order of likeness between a given set of observers and a reference observer in evaluating the absolute specification of colors (see Table VII in Ref. 4).…”

“…(5) and (6) are dependent upon the superindex j, whereas this is not the case in Eqs. (3) and (4). This result arises from the fact that the SPD's are metameric for the reference observer, whereas metamerism is not preserved for the rest of observers.…”

“…Several analyses have been carried out to gain a further insight of this effect. [1][2][3][4] On the other hand, the sensitivity of the visual system to small color differences has been an area of intense activity since the pioneering work of MacAdam. 5 In that work, the elliptical geometry was adopted for representing the thresholds of chromatic discrimination.…”

An analytical method to determine how colormatching functions influence the perception of chromaticity differences is proposed. We show that, as a consequence of the observer metamerism, a metameric colormatch perceived by one observer may appear to be a significant mismatch to a different observer. It is also shown that, on average, the differences between the color-matchings made by two different observers can be estimated to be in the order of 2 CIELAB units.

“…Several works have been carried out in order to gain further insight into this effect. [1][2][3][4] The influence of cmf's on the specification of color discrimination thresholds were analyzed by Melgosa et al 1 They found that the parameters characterizing the thresholds presented a weak variability. They also found significant displacements of the centers of the ellipses when considering several sets of cmf's.…”
