Construction and Application of Color Fiber Digital Color Mixing Model
In view of the lack of digital means to calculate the color mixing process of colored fiber,this paper aimed to build a full color gamut grid color mixing model.Three primary color fibers and gray fibers were selected for color mixing,and three groups of ternary double-coupled color mixing models with 10％gradient was constructed.The weight matrix,mixing ratio matrix and color value matrix of the full color gamut color mixing model were obtained by integrating four primary color nodes and three double-coupled color mixing grid point numbers.By converting cartesian coordinates and polar coordinates and substituting the color values of four primary color fibers,the full color gamut grid color mixing model of rectangular and circular panchromatic gamut and its chromatogram could be obtained.According to the constructed full color gamut color mixing model,the full color gamut meshing mixed color chromatography of different dispersion and the corresponding gradient color chromatography of hue,brightness and chroma were given,which was applied to the field of clothing fabric color design.The results showed that the constructed full color gamut color mixing model could not only obtain the visual color mixing chromatography of color fibers in the range of full color gamut,but also provided an effective means for the digital design of color yarns.
