该文就先天性红－绿色觉异常者对非彩色系表色色差的辨别展开了研究。结果表明，先天性红－绿色觉异常者色差识别的量值△Ｅ随目视评价的等级不同而异；先天性红－绿色觉异常者与色党正常者在非彩色表色辨别上存在一定的差异；同一明度等级上、下限的变化对先天性红－绿色觉异常者的非彩色表色辨别存在影响，这种影响与明度的级别有关。
In this paper, the congenital red - green abnormal perception of non-color system color-to-color separation has been studied. The results showed that the value △ E of chromatic aberration of congenital red-green vision abnormal persons varies with the grade of visual evaluation; there is a certain difference in the identification of achromatic color between congenital red-green vision abnormalities and normal parties The difference of the upper and lower limits of the same lightness level had an impact on the resolution of achromatic color of congenital red-green anomalous persons, which was related to the level of lightness.
