Abstract
Emergency evacuation signs as the urgent immediate egress or escape of people away from an area that contains an imminent threat, an ongoing threat or a hazard to livers or property, have become a measure of the level of urbanization development. However, there is still a phenomenon that different groups of people benefit unevenly from the color recognition of emergency evacuation signs. That is to say, there are obvious differences in the efficiency of color recognition of emergency evacuation signs among different groups, especially those with color vision deficiency (CVD) population. In the field of color design, color vision deficiency population’s color recognition of emergency evacuation signs is often neglected, which leads to many obstacles in reading the information of emergency evacuation signs in the process of color recognition. Therefore, the purpose of this paper is to optimize the color recognition of emergency evacuation signs for color vision deficiency population without affecting normal people’s color recognition of emergency evacuation signs, so as to improve the color recognition efficiency of emergency evacuation signs for this group. Firstly, this paper starts with the summary analysis of color recognition of color vision deficiency population, taking emergency evacuation signs as the starting point of research, establishing code of color design for emergency evacuation signs of color vision deficiency population. It is hoped that this color specification will not only provide an angle and direction in the field of emergency evacuation signs, but also in other areas of color optimization for color vision deficiency population.
