Paper Abstract

The objective of this project is to establish a practical application of the concept of Color Universal Design (CUD), the design that is recognizable to all color vision types. In our research, we looked for a clearly distinguishable combination of hues of four colors - black, red, green, and blue - which are frequently used in these circumstances. Red-green confusion people do not confuse all kinds of red and all kinds of green. By selecting particular hues for each color, the ability to distinguish between the four colors should be greatly improved. Our study thus concluded that, by carefully selecting hues within the range of each color category, it is possible to establish color-combinations which are easily distinguishable to people of all color-vision types in order to facilitate visual communication.
