The purpose of this study is to obtain data based on the readability of chromatic documents for use in visual environment design. That data would seem to be the same as the existing data based on the readability of achromatic documents. Experiments are undertaken in order to clarify the influence of color on readability. The results show that the same CIELAB color difference does not have the same influence on readability. In addition, it is thought that the equivalent luminance contrast is invariable irrespective of the size of a letter and is instead determined by the combination of the colors of the letters and the background. It is suggested that the readability of chromatic documents can be estimated by using the equivalent luminance contrast and the existing relationship between the visual factors and readability of achromatic documents.
