在铝阳极氧化染色配色过程中，通常依靠目测进行对色或以测色仪测试色相变化，再进行人为调整。此方式不仅准确度差，而且费时费力。为了解决目前配色产业所遭遇的困难，提升配色效率，以黄色和红色两种染料(EVERANOD YELLOW L-03和EVERANOD RED L-01)依照不同配比(100∶0、75∶25、50∶50、25∶75和0∶100)混合，测试了不同染色时间以及同一染色时间(15 min)、不同染色浓度下上色的L*、a*、b*值，再利用统计方法进行分析，找出L*、a*、b*的预估方程式，据此推算出上述不同条件下的L*、a*、b*值。结果表明，在不同染色时间以及相同染色时间、不同染色浓度下，L*、a*、b*的预估值与实测值差异都在8%以内，说明预估方程式具有一定的准确性。该方法可以节省试验时间，提高配色效率。

In course of dyeing anodized aluminum, the color matching usually was made by visual examination or testing the variation of color phases using a color tester, followed by artificial adjustment. This method not only has a poor accuracy, but also wastes time and manpower as well as resource. In this paper, to resolve the difficulties existing in current color matching industry and improve the color matching efficiency, two kinds of dyes EVERANOD YELLOW L-03 and EVERANOD RED L-01 were mixed with different ratios (100:0, 75:25, 50:50, 25:75, and 0:100), and the L*, a*and b*values of the colors obtained by dyeing for different time and by dyeing at different dye concentrations for the same time (15 min) were measured and then analyzed by statistic method to obtain the pre-estimating equations of L*, a*, and b* values, based on which the L*, a*, and b*values under different dyeing conditions can be calculated. The results showed that the differences between the pre-estimated and actually measured L*, a*, and b* values were all within a range of 8%, indicating that the established pre-estimating equations are accurate to some degree. The presented method can save experimental time and improve the color matching efficiency.
