An experiment was carried out under different light illuminance to verify the failures of color additivity and color
adaption transformation. In the asymmetric color matching experiment, many matched monitor colors are "bluer" than
the printed colors placed in the cabinet. The color additivity and adaption failures have practical consequences in
cross-media color matching. Different modification in different color region was used in the color adaption
transformation and the shift between the printed and monitor samples have been corrected to some extent. In order to
modify the color matching functions and improve the color adaption transformation, more experimental data were
required in the further research.
A series of printed samples on substrate of semi-gloss paper and with the magnitude of threshold color difference were
prepared for scaling the visual color difference and to evaluate the performance of different method. The probabilities of
perceptibly was used to normalized to Z-score and different color differences were scaled to the Z-score. The visual
color difference was got, and checked with the STRESS factor. The results indicated that only the scales have been
changed but the relative scales between pairs in the data are preserved.
