Do Human Factors Color Recommendations have any Practical Value?

Abstract

This study surveyed 342 directory-assistance (DA) operators regarding the text and background colors they used to display directory listings on their computer workstations. Color combinations were observed in use, recorded, and scored based on independent, published subjective ratings of color comfort and edge sharpness. Operators also answered a questionnaire that included information about: how often they changed colors and if they had experienced eye problems. No relationships were found between self-reported eye problems and observed color choices. However, operators using color combinations that were scored low on either comfort, edge sharpness, or both, were more likely to change the colors on their screens more frequently. This result provides evidence that independent ratings can provide practical guidance in making color recommendations.
