Colour dependency of textile samples on the surface texture

Abstract

In this paper, the perceptual and instrumental effects of texture on colour is investigated, using 63 textile samples, in nine colour centres and seven texture structures. The effectiveness of texture is evaluated by assessing colour differences between six texture samples and a standard texture in each colour group. Experimental results show that the sample texture has a significant effect on the measured and perceived colour and its influence depends on the colour centre of the sample. The magnitude of texture effect is more dependent on the texture type than on its coarseness. A new term to evaluate texture difference of a pair of textile samples was defined using a Gabor filter (Gabor texture difference). The visual colour changes gave a good correlation with Gabor texture difference values; however, the colour of the samples affected this correlation. So the colour change, as a result of texture differences, depends on two independent variables consisting of the Gabor texture difference and the colour centre of samples.
