Visual effects of wall colours in living rooms

Abstract

The visual effects of wall colours were quantified as the purpose of basic research to create a comfortable atmosphere by applying the visual effects of colours to interior colour design. The experiment was conducted at three different temperatures of 10, 25 and 40°C, and at a constant relative humidity of 60%. Slides of 1/10-scale living room models of different wall colours were presented to 30 Department of Dwelling students, who were instructed to judge the presented slides on seven-point bipolar scales according to 16 pairs of adjectives. The results of variance analysis revealed the effect of room temperature on some semantic scales. Three dimensions ‘activity’, ‘evaluation’ and ‘warmness’ were extracted by factor analysis. Analysis by the theory of quantification I showed that dimension 1, ‘activity’, was most greatly affected by the brightness of the wall colour, dimension 2, ‘evaluation’, by the saturation and dimension 3, ‘warmness’, by the hue.
