For super light and super deep undertone matching, it can be directly dyed with reactive or paint, which is convenient and intuitive, and has little effect on the undertone. But for deep undertone, direct undertone will cause great discoloration. Although this factor can be taken into account when undertone is dyed, the two-color product itself and undertone affect each other very complex, and there is no small simulation setup. It is not realistic to synthesize the background color by two kinds of colors. Although a few colors can be hard to come up with, for a large class of products, this method is not easy to operate, so the face color of authentic two-color products is mainly reactive dyes on one-sided dyeing machine. In practical production, the combination of deep vulcanization bottom and active bright surface has better effect, convenient operation and stable quality. Frost dyeing products are quite upscale, but the difficulty of this variety lies in the control of the ratio of face to bottom. On the one hand, it is the basis to master the degree of frost whitening, on the other hand, the thickness of the color should slightly exceed the height of the stripped color, so that it looks not only thin, but also fuller.
