Color and Vision Science Lab
Machine-translated · View original
Research in color science that applies the diversity of color vision to design.

AboutAbout the lab
Applying how people see color to design.
Prof. Sunaga specializes in color science and vision science, and studies human visual information processing, especially color vision.
Based on the understanding that the mechanisms of color vision are diverse, the lab also works on applying this knowledge to design.
Research themes include Color Universal Design and the design of educational programs on color vision diversity for elementary school children.
Key terms
- Color Universal Design
- A color design method that takes the diversity of color vision into account and ensures that information conveyed through color reaches people regardless of their color vision characteristics
- Color vision diversity
- The view that the mechanisms by which people perceive color are diverse, and that not everyone sees the same colors
- Dichromacy
- A type of color vision in which it is difficult to distinguish confusion colors (combinations of colors that are hard to tell apart)

The lab studies human visual information processing, especially color vision, and works on applying this knowledge to design. Research themes include color vision deficiency, psychophysics, Color Universal Design, and education on color vision diversity.
*Illustrative imageColor Universal Design
Taking the diversity of color vision into account, the lab develops color scheme methods that convey information through color regardless of a person's color vision characteristics. It works on a method that starts a color scheme from how colors appear to people with dichromacy, and on producing apps and color swatches that put this method into practice.
*Illustrative imageEducation on color vision diversity for elementary school children
There is concern that learning about color in school art and handicraft classes can create difficulties for students with color vision deficiency. The lab works on designing educational programs that let elementary school children learn about color vision diversity through experience.
Systems that accommodate color vision diversity
The lab studies the design of systems that accommodate diverse color vision characteristics, such as creating environments in which no one is left unable to obtain information because of differences in color. It also conducts research that organizes the elements included in the concept of color vision diversity.
