The purpose of the paper is to verify whether or not the following conjecture is valid: it is necessary for some respondents to change colors for three-period sequences of warm-colored and cool-colored facades until the second time period. The examination suggests that the conjecture is valid to warm-colored facades if a small change is made to brightness and saturation. In order to make a suitable change to colors, an evaluation function is required to be estimated at each time period because the represented preference orders over stimuli of periods are in general different.
