Paper Abstract

Our projects are founded on the principles of Color Universal Design (CUD), the objective of which is to promote public information systems, such as train maps, which feature colors recognizable to all color vision types1). In this paper, we were looking for a red which would be clearly distinguishable protan-vision people who see some tone of red as a dark color and consequently confuse it with black. These potentially kinds of red were represented on the Yokohama City Subway map, which we were presented with. We at the CUD believe it is possible to establish color design which is easily distinguishable to people of all color-vision types in order to facilitate excellent visual communication.
