Development of Color Universal Design Education System

Color is one of the most important elements in design. From an educational standpoint, while teaching and communicating with people who have different types of color vision wherein colors are difficult to distinguish is possible, no systematic educational method that allows them to experience such colors firsthand currently exists. Despite the fact that color is a crucial factor in design activities, individuals with different color vision face unique challenges that must be considered. Color vision is categorized into five main types, which include the typical vision and other types such as P-type and D-type. For example, individuals with certain types of color vision may struggle to distinguish commonly used colors like red and green.The concept of Color Universal Design (CUD) aims to create color schemes that can be used seamlessly by individuals with different types of color vision. Many related studies present considerations for designing with accessibility in mind, and these principles are widely applied in the field of design. For instance, selecting appropriate colors, adjusting contrast levels, and incorporating non-color-based design elements such as shapes are essential. This kind of practice is typically taught through in-house workshops and on-the-job training. However, the current study argues that to design effectively for individuals with different types of color vision, to experience their perspective as closely as possible is crucial. Furthermore, gaining such realistic experiences can foster greater awareness and understanding.This research systematizes the concept of CUD into a structured body of knowledge that facilitates understanding and practical application and develops educational tools. Specifically, a tool and framework utilizing cards with colors that are difficult to distinguish were developed along with a workshop design that employs glasses simulating different types of color vision. By using physical cards rather than solely relying on digital displays, this approach broadens the scope of educational and experiential opportunities.A testing workshop with collaborators was also included. During the workshop, participants were interviewed to identify issues and systemic shortcomings. Based on these findings, an ideal educational framework was proposed and key considerations for CUD-focused color education outlined. These insights are intended to inform future educational efforts for individuals with diverse types of color vision. This study assessed the educational effectiveness of the tools and methods.The ultimate goal is to create a tool that students and designers can use to apply CUD knowledge in their future design practices.
