The main purpose of coloring an object is to add information and to draw attention to it. However, the visibility of the visual object must not be spoiled by taking these effects too seriously. Explaining the influence of color on the visibility of an object is thought to be useful in showing the effect of coloring except for the visibility after securing the visibility. Our final goal is to establish a visual environment design based on the visibility of a chromatic object. We explain the influence on the visibility of the color quantitatively. The results of a subjective evaluation experiment are shown. The experiment has various conditions systematized by color difference (lightness, chroma, and hue under the CIELAB color system). The readability of chromatic documents was understood by focusing on the color difference as an index that quantitatively shows the degree of influence of the color on visibility. The relationship between the color difference and the equivalent luminance contrast described to discuss the influence of the color is shown.
