공공건물 안내사인의 유니버설 색채디자인 연구

Background Public buildings are spaces visited by a variety of people, and therefore, a universal design perspective is needed in sign planning. The purpose of this study is to examine the differences in visual perception of colors among users with various characteristics and to propose a color design method for public building guide signs. Methods In this study, a user survey was conducted to find a plan for signboard color planning that consider both functional and aesthetic aspects. In Survey 1, 7 types of samples werederived from the analysis of public building guide sign types and the contents of the upper color universal design guidelines were evaluated. In Survey 2, a follow-up survey was conducted to find more vivid colors, analyzing the visual perception differences by user group for 12 samples. A functionality evaluation was conducted for the user group that viewed the image in which the general/cataract/color-weakness visual data was reproduced, and an aesthetic evaluation was conducted for the designer. Results In the group that viewed the images with General,Cataract,andColorDeficiency vision, accent color combinations with low to medium brightness were functionally evaluated. In the group that viewed the images with ColorDeficiency vision, accent color combinations from medium brightness to high brightness were functionally evaluated. In terms of universal design, when the visual perception of the group that viewed the images with General/Cataract/ColorDeficiency vision was comprehensively considered, the combinations of medium brightness and high saturation maximized the contrast between the background and foreground colors to increase visual salience, identifiability, and legibility, whichalsosatisfiedaesthetics. Conclusions This study is significant in that it analyzes the color application of guide signs used inside public buildings from various angles and suggests universal color sign design standards that can convey information to users more effectively.
