With a comprehensive interface design, users can save time and improve their efficiency. Taking subway maps as an example, this study is about how color differences enable users to distinguish target item within reduced time. Two experiments were conducted in this study. The first experiment was conspicuity experiment. The second experiment was the conspicuity model test. The first experiment discusses how the influence of colors on visual conspicuity can result in different reaction time period of users. Therefore, the color lightness, chroma, and hue are separately analyzed, and the location of items on the subway map is included as an influencing factor to discuss how the conspicuity of the subway map will be affected. The visual conspicuity was defined in this study as reciprocal indication of reaction time. Observers were asked to find the target in subway map as soon as possible, and their reaction time was seen as the conspicuity of maps with different colors. In the second experiment, conspicuity model was developed based on the result of the first experiment, generating predictive conspicuity model from lightness, chroma and hue. It is found that when the color between the target item and the interference have greater differences, it creates better visual conspicuity. Also, when the target item is closer to the center of the screen, the conspicuity increases. According to the visual conspicuity model, a better effect on conspicuity is generated when R=0.88. This study can be provided to designer as a color matching reference.
