The aim of this study is to measure sensitivity reaction of human being with a physical properties of color and average size of particle for building materials and predict the influence of color and average size of particle in evaluation of building materials. As a results, 1) In results of qualitative evaluation construction, all 16 adjectives were extracted by higher evaluation items and ,total 14 adjectives were extracted as evaluation adjectives except adjectives of a contrary concept in each other. 2) According to the result of factor analysis, all 4 group of $ulcirner$potency$lrcirner$, $ulcirner$activity$lrcirner$, $ulcirner$evaluation$lrcirner$, $ulcirner$warmness$lrcirner$ were extracted. In this time, $ulcirner$potency$lrcirner$ as the first factor indicates the most hign original value. Consequently, $ulcirner$potency$lrcirner$ factor have an hign influence in evaluation of building materials. 3) As a influence analysis of evaluation variable by evaluation item $ulcirner$potency$lrcirner$ factor have an high influence by influence of average size of a particle, $ulcirner$activity$lrcirner$ factor have influence hignly by influence of brightness, $ulcirner$evaluation$lrcirner$ factor have an hign influence by influence of average site of a particle and the hue, $ulcirner$warmness$lrcirner$ factor have an hign influence mainly by influence of the hue
