Analysis of the color of the sample We use the accumulated swatches as a reference for coloring, and compare them with the swatches of Christmas tree special materials, trying to find a swatch with a similar color, but there is none. After looking up some information, there is no similar color, so we can only rely on experience to judge which color to use. After careful observation of the samples, it can be concluded that the samples are composed of three colors: green, yellow and black, with green as the main color.
