Abstract

Background The colors used for industrial safety signs are visual elements which instantly convey information regarding dangers resulting from accidents, and therefore must be carefully selected and determined considering the diversty of individuals’color recognizing capabilities. Acoordingly, industrial signs currently being used are required to use prominent primary colors, but in cases where these colors are used together the contrast between the colors is reduced, making the signs harder to read, especially for those with color blindness. Therefore, this study suggests color Arrangement guidelines (manuals) for industrial safety signs fit for persons with color blindness. Methods This study analyzed the visibility of industrial safety signs recognized by persons with color blindness based on a color vision defiency simulation. Based on these results, a famework for developing industrial safety signs which persons with color blindness can read was deduced. Result As a result, the brightness difference was determined to be the element which affected visibility the most based on researching the visibility of domestic industrial safety signs’ according to the visual characterstics of color blind individuals. From this, a research model for determinary the adjustments to brightness which can increase the the readability of industrial safety signs was produced. Conclusion This study suggests a color development model for reducing the range of error in the color perception of color blind persons. Further studies studies modifying necessary elements of color adjustments are currently in progress, and it is anticipated that this study will be more easily utilized in diverse industrial areas.
