Color Universal Design.jpg
People see color with significant variations. In Japan, there are more than 5 million people in total who see color differently from ordinary people, due to their genetic types or eye diseases. Color Universal Design is a user-oriented design system, which has been developed in consideration of people with various types of color vision, to allow information to be accurately conveyed to as many individuals as possible.

    1. Choose color schemes that can be easily identified by people with all types of color vision, in consideration with the actual lighting conditions and usage environment.
    2. Use not only different colors but also a combination of different shapes, positions, line types and coloring patterns, to ensure that information is conveyed to all users including those who cannot distinguish differences in color.
    3. Clearly state color names where users are expected to use color names in communication.

+1 Moreover, aim for visually friendly and beautiful designs.

Why is Color Universal Design so important now?

In 21st century society, use of color is increasingly becoming an important means of information transmission. Several years ago, for example, black and white printing was the norm for newspapers, magazines, textbooks and general publications. But recent development of color printing technology has dramatically turned them into color.These days, even simple guide maps would look rather inadequate unless they were in color. Color has also been introduced to the operation screens of photocopiers, or mobile phones, automatic ticket-vending machines, automatic teller machines (ATMs),etc., and most such screens are now in color. The use of a variety of colors has also become the standard for electronic information boards. Electronic devices and home electric appliances used to have pilot lights with a simple on/off function, but they now commonly come with new types of lights which illuminate in a number of colors to convey information in various different ways. Color-coding is in place in public facilities, museums, exhibition sites, etc., where rooms and areas are divided according to theme colors and full of colorful information displays. At railway stations, train lines are color-coded for direction purposes; route maps and time tables are illustrated with lines and characters in a variety of colors.
