报道了中国人眼对表色色差辨别的实验研究中非彩色系列实验研究结果，并与国外有关结果进行了比较。结果表明，非彩色的明度特性变化，对人眼色差辨别无显著影响，色差值仅随目视评价的感觉等级不同而异。此结果与国外有关报道的结果基本一致。实验结果为中国颜色体系的非彩色系颜色样品提出了色差宽容度：△Ｅ＜１．５。此色差宽容度已被全国颜色标准化技术委员会认定为ＧＳＢＡ２６００３—９４《中国颜色体系》国家标准中颜色样品色差宽容度的技术参数。
This paper reports the results of a series of experimental studies on the non-color series in the experimental study of Chinese people’s eyes on the color difference of the color, and compares the results with those of other countries. The results showed that the change of the brightness characteristics of achromatic color had no significant effect on the color difference of the human eyes. The color difference value only differed with the sensory rating of the visual evaluation. This result is basically consistent with the results of foreign reports. The experimental results proposed color tolerance for the non-color system color samples of China’s color system: △ E <1.5. This color tolerance has been the National Standardization Technical Committee of color as GSBA26003-94 “China Color System” national standard color samples tolerance of color tolerance technical parameters.
