The effects of the spatial frequency and size of stripes on the hue appearance of striped woven fabrics

In this research, the effects of the spatial properties, that is, spatial frequency and size, of stripes on their color appearance in striped woven fabrics were investigated. The lightness, colorfulness, and hue of stripes in three types of 180 striped fabrics, in which stripes were arranged in different spatial frequencies and sizes with different adjacent colors, were visually estimated by observers. Through the statistical analysis of the visual estimates, it was found that the spatial properties of stripes affect their hue appearance, while their lightness and colorfulness appearances are not significantly affected. In general, when the stripes become thinner and increase in spatial frequency, their hues appear more different from their actual hues. These effects of spatial properties on hue appearance were found to become stronger with lighter and more chromatic adjacent colors. Finally, a prediction model of the combined effects of the spatial properties of stripes and the colorimetric properties of adjacent colors was derived, and its great predictive accuracy was proven through numerical and statistical evaluations. It is envisaged that not only will the findings of this research provide advantageous conditions to design striped woven fabrics with desired color appearances, but they will also be the foundation for modeling various color appearance effects that occur in bicolor or multicolor patterned fabrics
