This paper proposes the colors of characters suitable to presentation slides. We propose five color combinations. A combination has three colors of base, main, and accent colors. The base color is for the background. The color white is used as the base color. The main color is for the part becoming the frame. The accent one is for the place where we want to emphasize. The lightness differences between the base color and the others are considered. The color difference between these two colors is also considered in order to attain good visibility. The slides colored by the proposed color combinations are presented to demonstrate their effectiveness.
