The characteristics of human visual sense change widely according to the ambient environment. This study is aimed at measuring, on quantitative terms, the visibility of colored light in dense fog. Visibility was measured with four subjects, each with a normal color vision, using colored Landolt rings. As a result, it was found that in dense fog, the visibility of yellow color was at the highest level, and that of blue color at the lowest level : and the visibility decreased even with a larger particle diameter.
