For most cities in China, there is no sign color guideline of public spaces for aging cataract user. However, the color of public sign design considering the increasing number of elderly people is important in creating a pleasant mobile environment for users. Based on the universal design, this research explored the visual characteristics, and conducted field investigation and analysis of the major subway transfer stations such as Chengdu and Chongqing, which are representative cities in southwestern China. And this paper is to provide suggestion for the improvement methods of sign color guideline on the city’s public spaces. According to the visual characteristics of cataract and the requirements of general design, the Munsell color system was directly used to measure the color of Chengdu and Chongqing subway stations. Taking the difference in brightness between adjacent colors in the readability difference of 6 and above as the standard, this study found that Chengdu accounts for 5% of the total, and Chongqing accounts for 46%, which is significantly higher than Chengdu. According to the color readability of the adjacent color senile cataract as the standard of contrast color, the survey results show that the image color and background color of Chengdu and Chongqing are all black, white, gray and other colors. There is no contrast between colors, but gray contrast with other colors as well as the contrast between black and white.
