Abstract
The quantification of visual effects values of the wall colour applying to interior colour design was investigated. Each of the 1/10 scale models (presented as slides) that were different from the wall colour was judged in the same order on each bipolar semantic scale of the sixteen adjectives. The results were analyzed by factor analysis and quantitative analysis. 1) The results for the two methods, one 1/10 scale models were judged, and the other slides, were not significantly different. 2) Using analysis of variance, it was shown that the subjects responded differently to some scales, "warm-cool" "fine-groomy" "hot-cold" "broad-narrow" "lively-lifeless", in different environment temperatures. 3) Three dimensions were produced. Dimension 1 would seem to relate to how inspiring the room is, and it was named the factor of "Activity". The second dimension related to how much harmony the room has; how controlled it is, and it was named the factor of "Evaluation". The third group was clearly a warmness group, and it was named the factor of "Warmness". 4) Using the quantitative analysis of Hayashi, dimension 1, "activity", was influenced to a greater degree by brightness than the other factor of the wall colour, "evaluation" was influenced by saturation and "warmness" was influenced by hue. The higher values of brightness was, the more the living room had pleasantness and liveliness, and the higher values of saturation was, the less the living room had friendliness and satisfaction.
