| Background Color plays a crucial role in design as a medium for conveying information. However, individuals with color vision deficiency (CVD) experience difficulties in distinguishing certain colors, leading to unequal access to visual information in various environments. This results not only in inconvenience but also in significant limitations to rights such as the right to education, consumer rights, and even life safety. Despite the importance of this issue, previous research on design for CVD individuals has primarily focused on technical corrections or specific media, lacking a comprehensive analysis. Therefore, this study aims to compare and analyze trends over the past 25 years in domestic CVD-related design research, examining the types of media, changes in services, and application areas, and to propose a direction for future color universal design.
Methods To systematically analyze the trends and developments in design research for individuals with color vision deficiency, this study conducted a scoping review of 36 selected research papers. The PRISMA(Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were employed to enhance the reliability and validity of the literature selection and analysis. In addition,a snowball sampling method was used to expand the scope of the discussion and provide a more comprehensive understanding of the research landscape related to CVD design.
Result The analysis revealed that digital media allows for flexible design through real-time color correction and user customization, whereas print media, which is difficult to modify after production, relies heavily on non-color visual elements for information accessibility. In the early 2000s, design services for CVD individuals were primarily driven by technical approaches focused on color correction. Over time, these have expanded into universal design applications on web and mobile platforms. More recently, design strategies have evolved to include emotional UX and real-time adaptive interfaces. Public design tends to emphasize accuracy and normative clarity in information delivery, while market-centered design focuses on user experience, personalized interfaces, and emotional engagement.
Conclusion Design for individuals with color vision deficiency has evolved from simple color correction to an integrated approach that encompasses technology, emotional design, and user environments. In particular, recent advancements in data-driven digital technologies have enabled the development of interactive interfaces that support real-time adjustment, shifting away from static compensatory designs toward dynamic and participatory information systems. Moving forward, a comprehensive design strategy is needed-one that considers both universality and flexibility, and reflects both public and commercial design values through institutionalized color universal design principles. |
