Outline of Final Research Achievements

The study involving 16 college students aimed to examine the effects of different color combinations on VDT screens on their work efficiency and fatigue during 30-minute tasks. Sixteen color combinations in positive and negative display modes with blue backgrounds of varying levels of lightness and chroma were prepared. Although the work efficiency was significantly lower when the difference in the lightness of the colors of characters and background was the smallest and the screen was in the positive display mode, there were no significant decreases when the other 15 color combinations were used. An analysis based on the CFF, which indicates the levels of subjective fatigue and eye stain, suggested that the smaller the difference in the lightness, the stronger the feeling of fatigue. The students also experienced physiological and subjective fatigue when the contrast ratio between the colors of characters and background complied with the Web Content Accessibility Guidelines 2.0.
