ABSTRACT:
A color variation inducing device is positioned in contact with or in the proximity of or effects action through air blowing means on a thermally color-varying article provided with a thermally color-varying layer, thereby inducing color variation in the thermally color-varying layer. The device comprises an electrothermal converter device provided with a heat absorbing portion and a heat generating portion based on Peltier effect, a radiator connected to the heat generating side of the electrothermal converter device, and a casing for housing and supporting the electrothermal converter device, wherein the electrothermal converter device is rendered functionable under the application of a DC voltage in such a manner that the heat absorbing side thereof exhibits a temperature reduction of at least 3.degree. C. with respect to the ambient temperature, within an ambient temperature range from 10.degree. to 35.degree. C.
