Abstract
Conspicuity of color changes according to illuminance because of the Purkinje shift. This makes it difficult to design safety clothes with a single color which gives always high conspicuity at any illuminance. To overcome the difficulty the combination of two colors, one being very conspicuous at day time and the other at night time, was proposed to use for the clothes. To evaluate the conspicuity throughout different illuminances the conspicuity index was introduced as the sum of the conspicuity points of a color combination at three typical illuminances, 0.1, 10 and 1000lx. The indices were experimentally determined for 12 color combinations and it was shown that they agreed quite well with those of theoretical prediction.
