Color has been strategically used to attract consumers in the textile and clothing industry, and yarn color mixing is one of the most typical methods of imparting color to textile products. However, the fact that color appears different depending on the illumination has concerned textile designers and sellers at the point of color communication and sale. This study quantitatively analyzed how the color appearance of woven fabrics composed of single and multiple colors of yarns changes under a broad spectrum of illumination conditions. The lightness, chroma, and hue appearance values of 36 chromatic fabrics, in which red, yellow, green, and blue yarns were woven together, under 16 different illumination conditions were calculated. For the illumination conditions, correlated color temperatures (CCTs) of 2700, 4000, 5000, and 6500 K and luminance of 100, 1000, 4000, and 8000 cd/m² were employed. The color appearance values of fabrics under the 16 light sources were compared with each other and also with their true physical colors. It was observed that the ranges of the varying lightness, chroma, and hue appearances of fabrics ranged up to 8.49, 16.24, and 27.04, respectively, indicating the huge effect of illumination on color appearance changes. In particular, the lower CCT of light sources induced the larger lightness appearance changes of fabrics from their actual physical colors. It was also found that the magnitudes of the color appearance changes of fabrics induced by light sources differed significantly according to the number of yarn colors and the overall colorimetric properties of the fabrics.

在纺织和服装行业，颜色已被战略性地用于吸引消费者，纱线混色是为纺织产品赋予色彩的最典型方法之一。然而，颜色因光照而呈现不同的事实已经引起了纺织品设计师和销售商在色彩交流和销售方面的关注。本研究定量分析了由单色和多色纱线组成的机织物在广谱光照条件下的颜色外观如何变化。计算了红、黄、绿、蓝纱线交织而成的36种彩色织物在16种不同光照条件下的明度、色度和色相外观值。对于照明条件，相关色温 (CCT) 为 2700、4000、5000、²人被聘用。将织物在16种光源下的色观值相互比较，并与其真实物理颜色进行比较。观察到织物的不同亮度、色度和色调外观的范围分别高达 8.49、16.24 和 27.04，表明光照对颜色外观变化的影响巨大。特别是，光源的较低 CCT 会引起织物与其实际物理颜色的较大亮度外观变化。还发现光源引起的织物颜色外观变化的幅度根据纱线颜色的数量和织物的整体色度特性而显着不同。
