CIE發布最新出版品CIE 230:2019- Validity of Formulae for Predicting Small Colour Differences

CIE 230:2019 reports on the performance of colour-difference formulae based on the results of experiments to evaluate colour differences visually. The report addresses small colour differences of adjacent colours. Visual responses (V) are compared with calculated colour differences (E) using five colour-difference formulae: CIELAB, CMC, LABJND, CIE94, and CIEDE2000. A power-function (PF) correction is also included. Using the STRESS index, the performances of the colour-difference formulae are tested without and with the PF correction.[more]
