There are many discrepancies between visually perceived color-difference and that which is
quantified from an instrumental measurement when dark color samples are measured in the textile industry. The
samples were prepared to represent these dark shades and the values of the instrumental results from
conventional color-difference formulae(CIELAB, CMC, BFD, CIE94, LCD99 and CIEDE2000). Those of visual
assessment were compared. The experimental results show that the CIELAB formula gives the best performance
over other formulae, and the CIEDE2000 formula for the color-difference according to chroma presents the worst
performance. Therefore, we can say that the problems in color matching of dark shades are caused by imperfect
formula, because the results obtained from a color-difference formulae are different and the CMC which is used
as a standard color-difference formula in the textile industry is not correct. So, a revised color-difference formula
is proposed in this study, to account for these problems. |
