Diversity in Color Perceptions and Color Universal Design
Human eyes have several kinds of cells that perceive light. Because different individuals have different sets of such cells, there are instances where some people have trouble distinguishing between colors or color names.
To help users navigate easily, different colors are used in signage in town or public transportation, on the screens of electronic devices, maps, diagrams in books or textbooks, etc. Color universal design takes care to ensure that everyone can easily perceive such differences among colors. Slight modification of colors or paying extra attention to designs can make a marked difference in how easily people can distinguish between colors.
Color universal design started in Japan about a decade ago. By raising various actual examples, I will explicate the diversity in how colors are perceived and color universal design that caters to the diversity.
