Research Abstract |
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.
