Zusammenfassung:	PURPOSE:To obtain a material for displaying the quantity of received light, which is non-toxic acid makes it possible to identify the degree of fading over a period of the initial stage of light reception to the final stage thereof with the naked eye, by causing the subtraction of colors in proportion to the quantity of received light. CONSTITUTION:A material for displaying the quantity of received light causes the subtraction of colors in proportion to the quantity of received light. The material reduces the screening ratio of light having a specified wavelength in proportion to the quantity of received light. Namely, it is a material which allows the transmittance of light having said wavelength to be increased. For example, when the material is phycoerythrin extracted from the cell of algae of Rodophyceae, the screening ratio of light having a wavelength of 550nm, which is received by phycoerythrin, is reduced and deep red is faded from pink to colorless as the quantity of received light by deep red phycoerythrin is increased. Thus, the quantity of received light can be simply measured by the degree of fading with the naked eye. The quantity of light having a wavelength of 280-700nm, pref. 450-600nm can be displayed with good accuracy.
