摘要：
In order to provide a reference for more suitable color difference formulae for textile industry in trade and quality control, the uniformity of 3 main and 1 newest formulas was studied by utilizing Sino Color Book (SCB) with the largest number of internaterial samples (nearly 20 000) and good visually equidistance, their chromaticity parameters were measured by the X-Rite spectrophotometer, and then more than 30 000 pairs of adjacent color samples in SCB were selected from three directions of hue, chroma and depth, respectively. Their color differences were computed by MatLab programming and their statistic data of average, and CV values and performance factor were analyzed. Results show that different evaluation indexes in different directions exhibit different effect. For the uniformity of the 4 color different formulas: CAM16-UCS is the best, and CIEDE2000(2:1:1) is slightly better than CMC(2:1), and both are obviously better than CIELAB. For the value order of the 4 color differences: CIEDE2000(2:1:1) < CMC(2:1) < CAM16-UCS < CIELAB. Copyright No content may be reproduced or abridged without authorization.
