Relations between psychological visual images of exterior wooden walls and their visual physical characteristics were investigated. Forty-two photos of different weathered wooden walls ware distributed to 18 male subjects and 19 female subjects and were arranged in orders according to "Furusouna (aged)", "Yogoreta (dirty)" and "Kanjino yoi (good impression)". These three words have high correlation between each other. Especially "Yogoreta (dirty)" and "Kanjino yoi (good impression)" have extremely high correlation between them (γ=-0.983). Wooden walls with low lightness L^* and low chroma C^* give us "Furusouna (aged)" image. Average difference of hue between adjacent mosaics i.e. ΔH°_<12×12> has high correlation between these three phychological images. Prediction formula for "Furusouna (aged)" I_a obtained by multi-regression analysis is I_a=2.492×log (ΔH°<16×16>)-0.027×L^*av-0.555
