Robust Color Universal Design without Restricting Colors and TheirCombinations Using Lightness Contrast Dithering

本研究的目的是为了获得对不同光照条件下使用亮度对比度抖动近似的色彩通用设计方法的稳健性的基础数据。在三种照度(100lx，500lx，1000lx)和三种色温(2800K，5500K，8000K)的光照条件下，对亮度对比度抖动近似生成的颜色图案的可见度进行了评估。实验共对19名受试者进行。结果表明，在低照度下能见度降低，但色温变化不明显。

The purpose of this study is to obtain basics data for a robustness against different lighting conditions of the color universal design method using lightness contrast dithering approximation. Color patterns generated by lightness contrast dithering approximation are evaluated about visibility under different lighting conditions: three levels of illuminance (100lx, 500lx, 1000lx) and three levels of color temperature (2800K,5500K, 8000K). The experiments are conducted for 19 subjects. The results show that the visibility decreased in low illumination, but there are no significant difference about the color temperature.
