Evaluation on Size-Illusion of Clothing Color Based on Behavioural Measure

Size-illusion of color can affect wearing performance. In the current study, three styles of clothing and a rectangular piece whose area was similar to those of the clothing with various colors were evaluated in behavioral experiments. The purpose of the study is to explore the influence of saturation, brightness and hue of colors on size-illusion. Results show that size-illusion is most outstanding on the dimension of brightness, and it is more prominent on clothes than on color pieces. The picture with high saturation is bigger than that of low saturation, with high brightness or with longer wavelength displays an expansion effect. The size-illusion may be related with the background color.
