Four Years of Color Research for Visual Displays

This paper summarizes an investigation of the effects on human task performance of color coding in visual displays relative to coding by achromatic letters, digits, and familiar geometric shapes. The results of the investigation provide a comprehensive assessment of the potential advantages and disadvantages of color coding. It is concluded that color coding offers no special property for coding visual displays.
