摘　　要：[目的]探讨Lab色度系统与人眼视觉感受在评价黑白差异中的异同。[方法]采用Lab色度系统光谱光度计测量成对纸片黑白度差异（以L值差值表示），通过正常人群对每对纸片颜色深浅判别的正确率，分析Lab色度系统与人眼视觉感受的关系。[结果]L值差值在0～7时，人眼分辨正确率为20．00％-98，57％，男性较女性高，〈40岁人群较〉40岁人群高；当L值差值≥1时，67．14％的人视觉感受与Lab色度系统结果一致。[结论]Lab色度系统评价黑白差异时只有其差值≥1时，才能应用于美白化妆品的评价。[ Objective ] To study the relationship between Lab color system and human color vision on black-white discrimination. [ Methods ] The difference of L value was used to quantify black-white discrimination in a pair of paper sheets using spectrophotometer, The discrimination also was determined by human eye vision, [ Results ] When the L value differences are among 0-7, the accuracy of human eyes were among 20.00%-98.57% ; the accuracy of male was higher than that of female ; when the L value differences were higher than 1,67.14% of people could discriminate them correctly. [ Conclusion ] Only when the L value difference was higher than 1, could the Lab color system be applied in assessment of cosmetic.
