Traditional embroidery has rich colors, and there are mainly two color matching methods. One is the matching of contrasting colors. For example, we often see the matching of bright red and green in embroidery works. Polar color contrast can make the pattern more eye-catching. Usually, white or black is used as the background color to reconcile, stabilize the color relationship, and the visual effect is exaggerated but tends to be harmonious. This color matching style is common in many national traditional embroidery. For example, in Miao embroidery, the bold use of color, the use of red and green, purple and green, purple and black, etc. are usually considered to be the color matching methods of color matching taboos. However, in Miao embroidery works, a large number of white and black are used to reconcile, and the contrast produces visual contrast, with a stronger sense of hierarchy and three-dimensional, highlighting the beauty of simplicity. Another example is black-and-white embroidery, which uses black and white to set off each other, one light and one dark, and contrast each other to produce a distinctive three-dimensional feeling. Another common color matching method of embroidery is the coordinated simple and elegant color matching, which uses the same color system or similar color system to organize the pattern color. The simple and elegant color matching is soft and calm. For example, the color matching of Suzhou embroidery is famous for its elegance. The original colors are reconciled by overlapping color lines, and the color processing is exquisite and soft
